Re: [rules-users] modifying the problem facts while running the solver - Drools Planner

spinjala wrote THis is what is happening now with my sample solution that I am writing.. Once the solver finds that a workorder (WO1) couldn't be assigned to any resource in the list of resources (due to the constraints)... Well, it's a slightly different problem them. Planner's approach is

Re: [rules-users] Rule flows in Drools planner configuration?

spinjala wrote Is it possible to have a rule flow file that defines a set of rules (constraints) but executed in the order per the defined ruleflow.? I dont see any example doing that so I was wondering if it is possible at all to have the constraints defined with a rule flow file instead

Re: [rules-users] Any additional (better) documentation for the examples included in Drools Planner product?

Re: [rules-users] Planner 5.4 - Overriding CachedMoveFactory to skip some PlanningEntity instances

my error here in looking to extend CachedMoveFactory. Obviously, the moves are cached, and not regenerated each forage. I suppose if I wanted to achieved what I wanted, I'd just override isMoveDoable() to make it more discerning -- but,as the JavaDoc suggests, there's little benefit to doing

[rules-users] Planner - IntConstraintOccurrence not being retracted

I've been building a prototype similar to CloudBalancing. I've got IntConstraintOccurrence objects being inserted via insertLogical() through my rules. For some reason, I don't think these are being retracted as expected -- the count() of accumulated IntConstraintOccurrence's ramps up to 10x what

Re: [rules-users] Planner - Initialized solution local search

I figured out the problem. DefaultSolver.runSolverPhases() will go through each phase, and will revert the changes if they're not better. Or, more exactly, here are lines 191-193: if (it.hasNext()) { // solverScope.setWorkingSolutionFromBestSolution(); }

[rules-users] Planner - Initialized solution local search

I'm using v5.4. I've built a prototype which uses the constructionHeuristic, and localSearch, as the example does, and am able to run the solver (though it still doesn't do a good job of solving at this point). I've now added customSolverPhase, and set it to use an initializer class which

Re: [rules-users] Score curruption exception in drools-planner-5.4.0.CR1

Right, the root of the behavior is that TRACE enables assertWorkingScore(), which tells me that the workingScore (reflecting the score after the move) is not the same as the uncorruptedScore (reflecting prior to the change), and specifically, that 4 ConstraintOccurrences are mismatched. For some

Re: [rules-users] Planner - Initialized solution local search

re: /Double check if you aren't calling afterEntityAdded() on the non-initialized entities too. Also check that the construction heurstics run before the localSearch solver does (the order in which they are declared in the config xml matters)./ Checked both. I'll file a JIRA bug, but I'm just
