"Ever since I was young, I have enjoyed solving puzzles. When a supervisor of a project told me about Quintiq, I also came across the ComBUStion challenge. During my engineering studies, I already got in touch with modelling problems as MILPs during projects and my master thesis. I considered this challenge as a good opportunity to test my skills. A first attempt did not render the optimal solution as my model was tailored (too much) to the provided example. After reformulating some constraints, I managed to find the optimal solution in a second attempt with manual input. Not yet satisfied with the time, I learnt about automating the data input from a screenshot, and automated clicking for output. Hence, the programme managed to solve the problem in less than 30 seconds. During a third and last attempt my computer screen froze during the automated clicking, yet my time was less than 2 minutes. Regardless of the final outcome, I was more than proud of my achievements. Of course, it got even better when I received an email of Quintiq during the second day of my holiday! Altogether, it was a joyful challenge and, in my experience, the nicest and most original way to start an application procedure. Thank you Quintiq!"

"When I learned about the ComBUStion Challenge, I knew it was a puzzle for me. Obviously, scoring less than a perfect 100% was unacceptable to me. During my studies in Mechanical and Industrial Engineering in NTUA, I learned more in the field of Operational Research like heuristic search techniques, constraint, combinatorial, integer, linear and nonlinear programming. But still I had to learn more deeply in order to be sure that my score would compete in a worldwide arena. Although it is not my first time that I have excelled in an international competition, being best in a worldwide competition-puzzle set by Quintiq, the top high-tech company in the field of ultimate puzzles gives me great satisfaction. It is known, the roads of success and knowledge are always under construction and have many great puzzles, so I am looking forward to enjoying greater challenges ahead."

''During my studies in Econometrics & Operations Research in Groningen, I have learned how to solve different kinds of optimization problems. So, when I came across the Combustion challenge, I thought about giving it a try. In my first attempt, I tried to solve it manually without any optimization tool. Obviously, in this approach, I could not find the optimal solution. For this reason, I decided I could do better and fortunately there were two more attempts available. It was a real challenge to formulate the problem into a mixed-integer linear program, but ultimately I was able to integrate all constraints. The next step was to write a program that could solve it. My goal was to design a Java program that could read out the relevant information from the screen, solve the problem and click in the solution. It was a real thrill to see that my program solved the Combustion challenge with one mouse click.''

''I was already in middle of a recruiting process with Quintiq when I heard about the ComBUStion challenge. I figured I could enhance my chances to succeed in the recruiting process by scoring 100% on the challenge and getting my name on top of the leaderboard. My initial idea was that the problem could probably be solved by linear integer programming. Some additional research had to be done before I could convince myself that all the rules could be covered with this approach. The next step was to choose good open source tools for the modelling and solving the model. The actual modelling was the hardest part. Eventually my computer could find a 100% solution for the test data in 2 minutes and I was ready to try the real Puzzle. For this problem It took almost 40 minutes for the solver to find an optimal solution. Luckily this left enough time for the data extraction and feeding in the solution. Despite the poor final time I achieved my goal and solved my first ever linear integer programming puzzle. And what a fun puzzle it was. By now I have already received the best price I could imagine. I am a fresh Quintiq employee and I can continue solving interesting puzzles.''

''Participating in the ComBUStion challenge was real fun, since solving logical puzzles is one of my hobbies. Moreover, this clearly formulated real-life problem gave me a chance to employ my optimization skills. After examining the puzzle, I transformed it into a linear programming problem which I solved using existing software. Thanks to the short computational time, I could easily complete the puzzle within the given time even reading and writing the data by hand. I find the idea
of the ComBUStion puzzle great, since it provides an impression of the kind of work done in the company and gives me a chance to see whether such challenges make me tick. Thank you, Quintiq!''

"I stumbled across the ComBUStion competition when I was searching for companies that share the same interest as me in solving puzzles with optimization techniques. While browsing at Quintiq website, the ComBUStion puzzle immediately caught my attention. Looking at the leaderboard at that time, I knew in order to obtain the highest score, I need to find the optimal solution, and also solve it as fast as possible. By looking at the size of the puzzle, linear integer programming was the best option for me. This technique was able to find the optimal solution for a puzzle of this size in a short amount of time. So I modeled the problem and solved it with an open source software. I also designed an Excel spreadsheet to speed up the data entering process. ComBUStion puzzle is not only a fun competition; it also encourages people from all over the world to build interest in finding fast and efficient ways to solve puzzles. Thank you Quintiq."
- Joanne Chew
''I have solved this kind of problems during my studies, so I knew I could solve the problem. The challenge was to solve it as quickly as possible. As the problem was not too complex, I decided to model the problem as an integer linear program to make it fast. After I had tested the model by using the "how to play" -example I proceeded to next step, which was to automate the data entry and solution submission. Before the ComBUStion! Challenge I had not written a program, which would extract data from a picture or control the mouse. My goal was to fully automate the process. I did not quite achieve the goal, but as my semi-automatic program read input data from the screen, solved the problem and clicked the solution in less than ten seconds, I was satisfied with the speed. All in all, it was an interesting, challenging and rewarding puzzle, which also helped Quintiq to stand apart. Thank you!''
- Aleksi Seppänen
''This was a really rewarding fun! I love computational challenges, and one-off projects always give me room to try tools I would not try otherwise. Hence, I had to give the ComBUStion puzzle a shot. Needless to say, my goal was not less than winning it.
Mathematical optimization is one of my old loves. Some wind has blown us apart long time ago, so modeling this puzzle turned out to be a refreshing exercise. This part is not very hard, however some constraints need a careful reading.
But there is always a catch. Assuming you reach 100% score, it is only the speed of your solution which determines your position on the leaderboard. Solving a typical instance takes seconds for a modern solver, but data transfer to and from a solver easily means hundreds of clicks. A lot of the previous winners already mentioned that the latter should be automated. Well, I definitely wanted to avoid that work as much as possible. Though past leaderboards are not public anymore, I vaguely remember that not all previous winners were super-fast. Hence, my "careful" analysis suggested to take some risk, to not automate the output transferring, and to automate reading only about half of the input. If that is not enough, I still have two more shots. Well, the analysis turned out to be right. I played in a lucky month. One attempt of this half baked solution with 15 minutes of clicking was sufficient. Thank you, Quintiq! I wish good luck to the future players!''

''The software industry today expects the most optimal algorithms/solutions that are real-time, fast and scalable. Solving the Quintiq ComBUStion puzzle certainly sets you up for that glaring reality.
I have been solving production scale mathematical optimization problems for a little over a decade now. So when one of my colleagues introduced me to the ComBUStion puzzle, it sounded quite familiar. I quickly wrote a solution roughly within an hour, but there was definitely more work to be done to get a perfect score.
It was on my things-to-do list for a while before I actually got to it in June of 2016. I formulated the problem as a Binary Integer Program and implemented that using my favorite optimizer to achieve a 100% score. However the real challenge was achieving my personal target of taking less than 7 mins to solve the puzzle. I built another piece of software that would accept the parameters for that problem instance, call my Binary Integer Program and display the output in a way that can be easily fed into the Quintiq user interface. I finally managed to solve it in 7:02 mins. Overall, it was a thoroughly engrossing experience.''

''Already for a few months the words 'Quintiq' and 'ComBUStion' were on my to-do list, placed prominently above my desk. The puzzle immediately sparked my interest when I first found out about this challenge through a college classmate who had won it a few months earlier. When finally diving into the problem, I quickly realized that the time required was of crucial essence to compete. After constructing a BIP model to solve the problem and testing it on the provided example I therefore used simple Excel sheets to help speed up the data entry. After setting the bar, being the first contester of the month, the long wait began which luckily did not affect my position on the leaderboard. The inspiring and challenging puzzle was a great and fun way to show my optimization and modelling skills and to compare to world-wide competitors!''
- Sander Siemons
''I came across the ComBUStion Puzzle while browsing the internet for Operations Research related work placement opportunities.
I was intrigued after reading the description of the puzzle and decided to give it a go because I was learning something similar in university at that time. I constructed a mathematical model using the example in the “How to Play” section, but wasn’t sure whether my model was correct. So, I felt grateful that we were given 3 trials to solve the puzzle as I actually detected quite a number of problems in my initial model, which resulted in a completely incorrect solution. Luckily, I had the chance to fix those issues and managed to get the correct solution in my later trial.
The biggest challenge for me in the process of solving the puzzle was the data extraction and entry part. Reading the comments from past winners, I realised that many of them had been able to utilise tools to automate their data extraction and entry processes. By doing so, they had managed to solve the puzzle just within a few minutes. However, I didn’t have the knowledge or skills to do it that way. So, I could only do them manually, which takes up a longer time to solve the puzzle. I guess I was very lucky this month as I might have been on a similar level as the other players, giving me the opportunity to win the prize. Thank you for the prize, Quintiq! It has been an enjoyable learning experience for me.''
- Xiang Pei Lim
''When I started looking for a job after my PhD in Groningen, a colleague told me about the Quintiq ComBUStion puzzle. As difficult puzzles generally challenge me, I became immediately determined to achieve an optimal score in the shortest time of the month. Aside from that, I was excited with the opportunity to show my modeling and optimization skills. I first reproduced the example instance of the puzzle in MS Excel, in order to practice solving the puzzle by hand. As this obviously did not lead to satisfactory results, I developed an optimization model in AIMMS to do the job. I also built an interface to speed up the data entry process. After several months looking for an opportunity to be the fastest player of the month, I finally won the game this March. I found it really enjoyable to solve the ComBUStion puzzle and it brought me even more experience in optimization modeling.''

“I am a mathematician, but I see mathematics not only as a professional field. I see it as a lifestyle. When I learned about the ComBUStion puzzle I started with a detailed study of the problem statement. As result I developed a special “Sandbox application” which simulates the ComBUStion original application in order to test different search technics and design a proper search algorithm. Finally, I developed an application consists of three parts: Scanner for getting initial data from the screen, Solver for search the best possible solution and Clicker for posting the result back to the screen. Using this procedure, the optimal solution was found in a couple of minutes. It was a very interesting and complex challenge. And, of course, it was very exciting. Thank you, Quintiq!”
- Artem Stolyar
''I’ve always liked solving puzzles, so when a friend told me about the Quintiq ComBUStion challenge I became excited immediately. I started to develop a mathematical model to solve the planning problem based on the ‘How to Play’ example. This example was also useful to test the correctness of the model. In order to achieve a time fast enough to compete for the prizes the solver had to be automated completely. In the end, the solver was capable of reading the input from the screen, solving the problem, and processing the output by controlling the mouse. It was very satisfying to see the computer solve the complete problem to optimality.
The ComBUStion is a great innovative recruitment challenge that is a lot of fun to participate and the prize is a very nice reward!''
- Rutger Bakker
"When I discovered the ComBUStion challenge it immediately became clear to me that this problem was far more complex than any of the problems that I had encountered during my computer science education. After a couple of days of taking wrong turns and buses, I came up with a theoretical model that did correctly implement all of the required constraints. I then implemented my model and used it to solve the 'How to Play' page example. To my delight it immediately achieved a very fast and -above all- optimal score. Subsequently, the 'live' run went equally well and drove me straight to my final destination: the top of the leaderboard. The ComBUStion challenge was a great way to test my skills and a very fun way to spend my time!"
- Michael Hobbel
''I first learned about the ComBUStion puzzle from a classmate who had also won it a while back. During my study I had encountered many similar problems and it turned out not to be that hard for me to write a mathematical program that could solve the problem to optimality. However this was not sufficient to win because the best solution on the leaderboard was reached only in about 3 minutes. This meant that I had to automize the input and output procedure of my program as well. When I managed to do this, I tested my program using the example and it seemed to be working just fine. To increase my chances of winning I decided to wait until the last day of the month to run my program on the real problem. This turned out to be a good strategy because I beat the best score in my first attempt. For me the ComBUStion challenge was really fun to take part in and in the end it was very rewarding to get the best score of the month''
- Wouter Smeenk
''I first learned about the ComBUStion puzzle in a guest lecture for a planning and scheduling algorithms course. I was immediately eager to put my new skills to the test by modeling the problem and letting the computer solve it for me! The sample problem allowed me to fully prepare and test my solver before starting the first attempt. However, during the first attempt I realised that inputting the problem and solution by hand was very slow and error-prone. That's when I decided to augment my solver to automatically read the problem from the screen and input the solution by controlling my mouse. This allowed me to get an optimal score in just a couple of minutes! The ComBUStion puzzle is a great way to challenge yourself to think outside the box for all those who are interested in optimisation problems!''
- Alexander Overvoorde
''When you deal with operations research, you cannot resist solving any optimization problem that comes up to you. When I read about the ComBUStion challenge it was immediately clear to me I had to take part in it.
I wrote down a mathematical model just a few minutes after reading the problem specifications, but the hardest part was to set up a quick interface for managing input/output data. The competition was very hard and luckily I managed to get the monthly leadership at my last attempt! It was a very exciting game, and a nice way to show off the potentialities of operations research in real-life situations. Also, I really appreciate the cool prize!''
- Fulvio Cappadonna
''One of my colleagues told me about the ComBUStion challenge. As I read the introduction, I immediately started to build up an optimization model for determining an optimal solution to the planning problem. After improving the data interface and performing some test runs, I was able to solve the puzzle very quick. The ComBUStion challenge is an interesting way to apply for a job interview and it was great fun for optimization specialists to demonstrate their modeling and programming skills.''
- Pascal Lutte
"I like the idea of getting a job interview by doing some challenge. I read that Google did it once and I searched the internet to look if more companies have used this idea. I didn't find anything, but later I found this website and I gave it a try. It's nice to win in general, but it's even nicer to win an iPad. So I gave it my best and now I have an iPad and they might give me a job. Very nice! If you think you have a chance, I encourage you to take some time to work out a nice strategy and win this game!"
- Paul Breeuwsma
"A colleague of mine told me about the ComBUStion challenge. When I checked it out, I was immediately hooked. Studying the detailed problem description, I recognized that it could be solved using methods I learned from university. So I started modelling and spent some time writing a program that would allow me to solve the bus drivers' optimization problem. That my program eventually found an optimal solution was extremely rewarding.
"The challenge was a fun way to see how the theory taught at university could be applied to solve real-world problems. Thank you, Quintiq, for this pleasant distraction from my daily routine."
- Hendrik Schaap
"The best puzzles are often simple to explain, yet require careful thought to solve. The comBUStion puzzle fits squarely into this category.

Quintiq's challenge is not only a lot of fun, it is also a playful representation of some of the company’s daily tasks. Thank you for this opportunity and the cool prize!"
- Walter Sebastian Gisler
''The ComBUStion puzzle was the perfect way to show off my modelling and programming skills. The planning problem was related to my master's degree area of study, so solving the puzzle was an interesting challenge. After programming a smart code and introducing a friendly-user interface, I was able to achieve the perfect score in a few minutes. It was a real pleasure to be rewarded as the winner of the month and I would like to thank Quintiq for this great gift. This puzzle was a good way to give me a simplified picture of Quintiq problems and it further motivated me to start a career in operational research.''
- Etienne Baghuis
''The ComBUStion puzzle is a very well thought-out challenge and a clever way to recruit new talent. It gives you a feel of the kind of problems present in planning and optimization. The pursuit of the perfect score against players from around the world is captivating. If you have a problem-solving mind, you cannot really do your victory dance until you know you have found the optimal solution!
