[rules-users] Re: the n best solutions on a very simple test case (drools-solver)

Only the solution which is reached by each chosen step is send to the BestSolutionRecaller. If you do only one step, you 'd have to do some dirty hack to get those other 4. Maybe you can use your current Finish combined with AND and a at least 4 steps taken finish, to force at least (4 - 1 = )3 steps. Combine it with a completeSolutionTabu of at least 3 (usually I take a 1000) and you 'll have 4 distinct solutions. Your starting solution will also count as one. But I am interested in this use case :) 1) Why do you want to recall you best 4 solutions? Only the best solution seems relevant to me (but I could be wrong). If this is a genuine use case, I can add a MultiBestSolutionRecaller in the drools-solver code. 2) Extending a BestSolutionRecaller is easy, but how did you hook it up into the framework? a) Did you build your solver and then do a setBestSolutionRecaller() b) Or did you use xstream ability to configure in your BestSolutionRecaller implementation directly? BTW: other feed-back on how to improve drools-solver is welcome With kind regards, Geoffrey De Smet Laurent Michenaud schreef:
