Hi,

I'm trying to find an issue that I expect to be a score trap.
As Geoffrey pointed out I enabled TRACE logging, which produces a rather big file.

Is there documentation on how to interpret the content?

There are some things that I do not understand:

1) I see sometimes this type of logging:
TRACE main org.drools.planner.core.localsearch.decider.DefaultDecider - Move index (249), score (-484hard/0soft), accepted (true) for move ({T= Inspect B747-AX.I#0 [P1] Kristof IV} <=> {T= Inspect A311-DX.I#1 [P1] Gerald IV}).

What does the <=> mean in this logging? What does the move actually do in this case?

2) TRACE main org.drools.planner.core.localsearch.decider.DefaultDecider - Move index (273), score (-5562hard/0soft), accepted (true) for move ({T= Inspect B747-AX.I#0 [P3] Kristof IV} => (P9) ).

This line indicates that the move is accepted. Is a move accepted before validating the rules or after? And in the same way does the score (-5562hard/0soft) indicate the score before or after the validation of the rules?

Can someone give me some directions, please?

Thanks,

Michiel
