[jboss-jira] [JBoss JIRA] (JBRULES-3367) Planner: score calculation with plain old Java

[ https://issues.jboss.org/browse/JBRULES-3367?page=com.atlassian.jira.plug... ] Geoffrey De Smet updated JBRULES-3367: -------------------------------------- Description: Provide an plain old java alternative to score calculations, so the user has choice (= freedom): - A) Drools score calculation (default). Does incremental calculation automatically, without extra code. - B) Java non-incremental score calculation. Very easy to reuse existing score code, but not fast. - C) Java incremental score calculation. Requires incremental boilerplate code, but experiments show that in some use cases (with little rules) it can be a 100 times faster than A) with drools 5.3. Note that undo-then and JIT compiling might change that number drastically in future drools versions. Technically, it's a matter of overwriting SolutionDirector. For C) we'll also need to adjust the Move and ProblemFactChange interface accordingly. was: Provide an plain old java alternative to score calculations, so the user has choice (= freedom): - A) Drools score calculation (default).
