Geoffrey,<br>
<br>
Thanks for your response.<br>
Indeed I use Simulated Annealing with maximumSecondsSpend. So
that explains the randomness of the LocalSearchPhase.<br>
Sorry for not remembering.<br>
<br>
Can you tell me please some more on "Use of HashSet in your
Solution class"?<br>
Do you mean a planning fact as a HashSet?<br>
</div>

no, just entities and values, no worries :)<br>

That's fine.<br>
<br>
The entity collection is best not a HashSet/Map, because FIRST_FIT
(as well as some entity selectors) will take the original order of
the entities to do things.<br>
With HashSet/Map, that order changes because Object.hashCode()
returns different ints, placing elements in different HashSet
buckets, which results into a different order.<br>

<div>As I read here
(<a class="moz-txt-link-freetext" href="http://docs.jboss.org/drools/release/5.5.0.Final/drools-planner-docs/html_single/#d0e3120">http://docs.jboss.org/drools/release/5.5.0.Final/drools-planner-docs/html_single/#d0e3120</a>)
this mode should produce a reproducible result.<br>
Though, even with o nly the construction phase
enabled, I get different results from sequential
runs on the same machine with the same code.<br>
Of course full solution (with LocalSearch) results
in different outcome too.<br>
<br>
How is this possible?<br>
<br>
Thanks<br>
