- 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.
- CSPlibDataset
CSPLib is a library of test problems for constraint solvers.
- CVRPlibDataset
Instances for the CVRP challenge.
- Free the world from wasteful scheduling with Timefold AIVideo
Solve NP-hard optimization problems with Timefold AI.
- 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.
- Optsicom ProjectDataset
Instances for several interesting NP-hard problems.
- 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.
- QAPlibDataset
Instances for Quadratic Assignment Problems.
- 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 OR-LibraryDataset
OR-Library is a collection of test data sets for a variety of Operations Research (OR) problems.
- 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…
