ANT/OR Operations Research methods

Methodologically, the ANT/OR group focuses on the development of heuristics, i.e., optimization algorithms that do not guarantee to produce the optimal solution. These algorithms tend to be orders of magnitudes faster, easier to develop, and more flexible than their exact counterparts (that do guarantee the optimal solution). For each optimization problem tackled, the algorithms developed and studied within the ANT/OR group rely on the state of the art in metaheuristic design, although exact methods and matheuristics (combinations of exact methods and heuristics) are also used when appropriate.
