Hyperheuristics

A hyperheuristic automates the decision which heuristic(s) to use on a specific data set.

A future version of Timefold will have native support for hyperheuristics. Meanwhile, it’s possible to implement it yourself: Based on the size or difficulty of a data set (which is a criterion), use a different Solver configuration (or adjust the default configuration using the Solver configuration API). The Benchmarker can help to identify such criteria.
