[rules-users] [planner] Questions about employee shift rostering example

[Geoffrey De Smet]

How can it need 2Gb of memory?

Drools Planner has 2 solution instances: the bestSolution and the 
workingSolution.

If you use solutionTabu of for example a 1000, it has a 1000 solution 
tabu's too. Your options:
1) Better cloning. See Examination: only the examlist is deep cloned, 
the periodlist, roomlist etc aren't even cloned.
2) Less solutionTabu, use the benchmarker. You're probably better off 
with a solutionTabu of for example 500 and moveTabu of 7.

With kind regards,
Geoffrey De Smet
