<br>
I'm trying to find an issue that I expect to be a score trap.<br>
As Geoffrey pointed out I enabled TRACE logging, which produces
a rather big file.<br>
<br>
Is there documentation on how to interpret the content? <br>

See logging chapter in manual and this image<br>

There are some things that I do not understand:<br>
<br>
1) I see sometimes this type of logging: <br>
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}).<br>
<div><span> What does the <=> mean in this logging? What
does the move actually do in this case?<br>
</span></div>
</div>
</blockquote>
<=> means it's a swap move<br>
=> means it's a change move<br>
Looks like it swaps all variable values of B747-AX and A311-DX

Unrelated: accepted means it's not tabu.<br>
Of all the accepted moves, the move with the highest score wins and
becomes the step.<br>

The score is the validation of the rules, after the move has been
applied.<br>
