Hi Geoffrey, Thanks for confirming and optimizing documentation. I think the thing which confused me is that in the doc (http://docs.jboss.org/drools/release/5.5.0.Final/drools-planner-docs/html...) does not say anything about RANDOM selection in the first (simple configuration) sections. If I am correct that even in the simple configuration this random selection is the case, then may I suggest this change:  7.4.1. unionMoveSelector  A unionMoveSelector selects a Move by randomly selecting 1 of its child MoveSelectors to supply the next Move. I know it's a very small change, but it takes away the doubt upfront. One more question concerning this chapter: In the advanced configuration section, the first example uses both selectorProbabilityWeightFactoryClass  fixedProbabilityWeight. Should one use these in combination? Or is it the one or the other? Also, in the second example only fixedProbabilityWeight is used. It seems strange to build a Factory that calculates the weight and in the same time to specify the weight hard-coded for every (some of the) child moveselectors. Am I right here?
