A curated index of Operations Research resources — solvers, courses, books, datasets, communities and more. Classified by type, topic and audience.
- AliGorithmVideo
YouTube channel with interesting knowledge about optimization.
- Anything you can do I can do betterVideo
Prof Marco Lubbecke talks about optimization in a TED Talk.
- ArcadeTSPGame
An arcade-style TSP challenge game written for https://github.com/tunnuz/arcadetsp's 2018 Christmas Party, follow the in-game instructions.
- Beer GameGame
Learn supply chain principles through a visual simulation.
- Burrito Optimization GameGame
Web-based app that is intended to act as an entry point for data scientists and problem solvers who could benefit from optimization; the game teaches players why optimization is valuable and important, why it’s difficult (by showcasing the scaling and added complexity of optimization throughout round play), and why solvers and other optimization algorithms are essential in finding an optimal solution.
- CSPlibDataset
CSPLib is a library of test problems for constraint solvers.
- CVRP GameGame
A game to better understand how CVRP works.
- CVRPlibDataset
Instances for the CVRP challenge.
- Free the world from wasteful scheduling with Timefold AIVideo
Solve NP-hard optimization problems with Timefold AI.
- Learn Graph TheoryGame
Interactive resources to learn Graph Theory.
- Learn ORGame
Interactive resources to learn OR.
- Lego ChallengeGame
The TLC is a simple constrained integer program turned into a game that you can play in a classroom with Legos. In each round of the game, your team acts as a boutique woodworking company who must decide which items to build and sell to the market. The goal is to decide how many of each type of item to build to maximize profits and beat other teams, where you are constrained by how many component pieces you have available.
- MathOpt: Solver Independent Modeling in Google OR-ToolsVideo
A new interface for Google OR-Tools.
- Mathprog-ORlibDataset
This site provides access to a number of Operations Research problem data sets.
- MIPLearnSoftware
An extensible framework for solving discrete optimization problems using a combination of Mixed-Integer Linear Programming (MIP) and Machine Learning (ML). MIPLearn uses ML methods to automatically identify patterns in previously solved instances of the problem, then uses these patterns to accelerate the performance of conventional state-of-the-art MIP solvers such as CPLEX, Gurobi or XPRESS.
- ML ain’t your only hammerVideo
Introduction to the field of mathematical optimization.
- Optimization Games for the YoungGame
Developed to help spark an interest for mathematics in children and young adults. I use optimization concepts in the context of real-life problems as motivation. All you need are a printer to print the pages with the instructions and a pair of scissors to cut out the game pieces.
- Optsicom ProjectDataset
Instances for several interesting NP-hard problems.
- Ponder This!Game
Seems some of us can't see a problem without wanting to take a crack at solving it. Does that sound like you? Good. Forge ahead and ponder this month's problem. We'll post a new one every month, and allow a month for you to submit solutions (we may even publish submitted answers, especially if they're correct).
- Pragmatic OR: Solving large scale optimization problems in fast moving environmentsVideo
Rubén Ruiz, Principal Applied Scientist at Amazon, shows how he leverages Hexaly at Amazon to solve a gigantic optimization problem that is out of the scope of other MILP solvers.
- Puzzles and GamesGame
A comprehensive guide to mathematical modeling with more than 140 games as case studies.
- QAPlibDataset
Instances for Quadratic Assignment Problems.
- Slick Oil GameGame
Deliver 100 barrels to the customer at the lowest cost. Select wells and refineries to choose volume flowing on pipe-lines.
- SNDlibDataset
SNDlib is a library of data for Survivable fixed telecommunication Network Design. Its purpose is to provide data about realistic telecommunication networks (including traffic) available to the research community.
- The Cutting PlaneGame
Learn about cutting planes in an adictive way.
- The Knapsack GameGame
A game to play the Knapsack to learn how to solve it.
- The OR-LibraryDataset
OR-Library is a collection of test data sets for a variety of Operations Research (OR) problems.
- TSP ChallengeGame
Another game with map visualizations for the TSP.
- TSP GameGame
Solve the TSP in a visual way from the Productions and Operations Management (Universitat Wein).
- TSPlibDataset
TSPLIB is a library of sample instances for the TSP (and related problems) from various sources and of various types.
- VRPlibDataset
This web is dedicated to the study of VRP; we have compiled here a great deal of information about it for public access: technical reports, many different variants of the problem, alternative algorithms and techniques for solving it, some well-known instances of the problem, the best-so-far solutions for those instances, bibliography, related links…
