I am looking for previous OR challenges.



My goal is :



  1. Applying my knowledge while solving problems suggested in those competitions; and/or


  2. If possible, reading solutions posted by participants.


I learned a lot about ML by reading solutions to kaggle competitions. I couldn't find any similar website for OR problems. It seems that the ML hype is eating up everything.

          The Helmut Schmidt Universitat contains a list of past, ongoing, and future contests in Operations Research.




          https://www.hsu-hh.de/logistik/research/challenges




          For example:



          • Active challenges: ITC 2019 on finding feasible solutions for organising student rooms and times.


          • Past challenges: PACE 2018 on Steiner trees on an undirected edge-weighted graph


          They are a considerable number of links to past events, though some of them have already been introduced in other answers, such as ROADEF.

                I personally like Project Euler. This website has mathematical problems that usually require programming to solve them. If you solve a problem you get access to the corresponding problem forum, in which users post their code and discuss their approaches.



                Admittedly, I consider Project Euler to be more about mathematics and computer science than about Operations Research. Still, there are plenty of problems that involve optimization, or to which OR techniques can be applied.



                I suggest the following problems for those with OR skills. Whether these problems are really OR is of course debatable, and the list is non-exhaustive: Problem 11, 18, 67, 68, 81, 82, 83, 84, 96, 122, 149, 185, 190, 280, 345, 392, 460, and 607.

                  Here is a link to INFORMS OR and analytics students team competition. You can also find the challenges for previous years and the presentations of the winner team. I believe you need to be registered in INFORMS in order to get the data.



                  https://connect.informs.org/oratc/home



                  Edit: in The Operation Research Challenge (TORCH)'s website, you can find the challenges and required data as well.

                  There is a competition section held during MOPTA (Modeling and Optimization: Theory and Applications), which is organized annually by Lehigh University. The competition is for students only and usually devoted to a practical problem and sponsored by a solver company.

                      There are the Makridakis Competitions, though they are infrequent. M-4 is just now getting finalized.

                                                I personally like Project Euler. This website has mathematical problems that usually require programming to solve them. If you solve a problem you get access to the corresponding problem forum, in which users post their code and discuss their approaches.



                                                Admittedly, I consider Project Euler to be more about mathematics and computer science than about Operations Research. Still, there are plenty of problems that involve optimization, or to which OR techniques can be applied.



                                                I suggest the following problems for those with OR skills. Whether these problems are really OR is of course debatable, and the list is non-exhaustive: Problem 11, 18, 67, 68, 81, 82, 83, 84, 96, 122, 149, 185, 190, 280, 345, 392, 460, and 607.
