Hi, If your class extends CachedMoveFactory, the drools planner will call your move factory only once at start. But if it extends AbstractMoveFactory, the drools planner will be call at each step Samuel CSC • This is a PRIVATE message.

Each iteration seems to get it's moves from this initial 'move pool' generated by the move factories. However, in the documentation it is mentioned that the move factory would be called for each iteration and would therefore allow me to modify the move generation algorithm for each iteration. So what is true for the current version of the planner 5.1.0? Can I configure different ways of using the move factories during the solution process? I'm using a standard tabu search configuration, based on the lesson schedule example.
