broken
------------------------------------------------------------------------------------------------
Key: JBRULES-2911
URL:
https://issues.jboss.org/browse/JBRULES-2911
Project: Drools
Issue Type: Enhancement
Security Level: Public (Everyone can see)
Components: drools-planner
Reporter: Geoffrey De Smet
Assignee: Geoffrey De Smet
Priority: Minor
Fix For: 5.2.0.M2
This code is bad in SimulatedAnnealingAcceptor:
// TODO don't abuse translateScoreToGraphValue
// TODO do hard and soft separately and then average their acceptChance
Double diff =
localSearchSolverScope.getScoreDefinition().translateScoreToGraphValue(scoreDifference);
if (diff == null) {
// more hard constraints broken, ignore it for now
return 0.0;
}
