<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>
