[jboss-jira] [JBoss JIRA] (JBRULES-3555) Allow to specify a relative value for the entity tabu

Allow to specify a relative value for the entity tabu ----------------------------------------------------- Key: JBRULES-3555 URL: https://issues.jboss.org/browse/JBRULES-3555 Project: Drools Issue Type: Feature Request Security Level: Public(Everyone can see) Components: drools-planner Affects Versions: 5.5.0.Beta1 Reporter: Lukáš Petrovický Assignee: Geoffrey De Smet Problems such as the RAS2012 challenge require us to provide a solution for problems of varying size - the number of entities in the various cases ranges from 3 to 30. In this case, it is nearly impossible to benchmark all those problems at once using the planning entity tabu. When you specify a tabu size larger than the number of entities, no solutions are accepted and thus the benchmark is useless. What I propose is to implement a planning entity tabu size that accepts the two different values: - Negative number. That would mean that the tabu would be ($size = $totalNumberOfEntities - $specifiedNumber). - Percentage. That would mean that the tabu would be ($size = Math.round($percentage * $totalNumberOfEntities)). In both cases, 0 < $size < $totalNumberOfEntities. This way, the planning entity tabu size will become universally usable.
