MCDMlib: Test Problems for Multiobjective Optimization

MCDMlib is a collection of test data sets for a variety of Multiobjective optimization problems.

The collection has been created in 1998. Unfortunately, the MCDMlib has been closed in 2007 and deleted by the host without archiving the website. Do not refer any longer the old URL ( which is definitively dead. Due to the important number of requests, the MCDMlib is coming back (July 28, 2010). The right URL to save in your bookmark and to refer is:


If you are maintaining a collection of test data related to a MCDM area and you are willing to share the material with the scientific community, please send us your URL. We will add the link here.


MOCOlib is a collection of test data sets for a variety of MultiObjective Combinatorial Optimization (MOCO) problems.

The description of the library and the test data sets are available using the following link:

Multiobjective Optimization Library

This library contains test instances for Multiobjective Discrete Optimization Problems. Namely, Three classes of test problems are used to generate random instances for multiobjective knapsack, assignment and integer linear programming problems. Besides, a method that generates all nondominated solutions for multiobjective discrete optimization problems with any number of objective functions is also available.

All this material, as well as further descriptions, are available using the following link:
