Consider the following constraint: ```java constraintFactory.forEach(Rule.class) .join(Shift.class, Joiners.equal(Shift::getRuleProperty, Rule::getProperty)) .penalize(HardSoftScore.ONE_HARD) .asConstraint("Rule violated"); ``` Assume `Shift::getRuleProperty` is an expensive method to evaluate. If a problem has no `Rule` instances, this constraint...

Refactors indexing in Constraint Streams so that the index supports random access to elements. This will be necessary for Neighborhoods. While here, I also noticed that the constructors of streams...

This PR enables sorting the value ranges at the `ValueRangeManager` level. The sorting feature is likely useful during the CH phase, and the new approach can address the sorting requirement...

Previously, Neighborhoods depended on joins on the left-hand side - these joins are, however, possibly massive. With large datasets, joining 100k entities with themselves would result in billions of entries...
