Re: [rules-users] OptaPlanner - best strategy for variable number of planning entities?

I solved the construction heuristic problem. Someone it didn't dawn on me right away that primitive types don't work properly as planning variables, because they're always initialized, thus the construction heuristic quits right away, thinking there's nothing to do. However, construction heuristic or no, it looks like it's getting stuck on local optima most of the time even in brain-dead simple cases (e.g. adding a constraint to force exactly one window). Not sure if I may need to add some custom move logic to account for the fact that there are many Boolean planning variables (one for each potential session to attend), but that most of the potential toggles don't make much sense (generally you'd want to either tweak the sessions on the edges of existing windows, or try killing a window and growing a different one elsewhere. -- View this message in context: http://drools.46999.n3.nabble.com/OptaPlanner-best-strategy-for-variable-...
