Re: [rules-users] planner: Solver-Phase after a ProblemFactChange?

When the solver is in the localSearch phase and a problem-fact-change
occurs:
will the solver jump back
into the construction-heuristics phase or continue with the local search?
it will
jump back, but only change the facts which have a null planning
value.
Reason for my question: We have a (chained) vehicle-routing-problem with a
custom SwapMove- and ChangeMove-SelectionFilter that return 'false' for
some moves (on immovable planning entities, e.g. when a stop should be
pinned to a specific tour etc.), but the solver modifies them nevertheless
after a problem-fact-change?
The new construction heuristics implementation (same
config) will fix
the immovable planning entity selector being ignored by the const heur
for 6.0, but that fix won't make 6.0.0.Beta1 :(
