Multi-Objective AI Planning: Evaluating DAE-YAHSP on a Tunable Benchmark

Mostepha Redouane Khouadjia, Marc Schoenauer, Vincent Vidal +2

All standard AI planners to-date can only handle a single objective, and the only way for them to take into account multiple objectives is by aggregation of the objectives. Further…
