Optaplanner SwapMove filter in Cheap Time -

-

i working on new planning problem , using cheap time testing. want add filter handle hard score constraint. in cases, machine cannot assigned - @ all.

i added filter swapmove filter:

public class taskassignmentfilter implements selectionfilter<swapmove> {  public boolean accept(scoredirector scoredirector, swapmove move) { taskassignment task1 = (taskassignment)move.getleftentity();     taskassignment task2 = (taskassignment)move.getrightentity();      if (task1.getmachine().getindex() == 0 || task2.getmachine().getindex() == 0)         return false;      return true; }

}

and added config

<swapmoveselector>     <filterclass>….taskassignmentfilter</filterclass> </swapmoveselector>

however, machine index 0 still assigned.

any hint doing wrong?

and possible handle constraint in score calculator also?

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
