[rules-users] Drools Planner examples applications running more than 10 minutes?

[Geoffrey De Smet]

Prabakar,

The alternative would be a custom algorithm, which will be slower than 
Planner.
However, you should limit how long you want Planner to solve. I'd 
recommend a short time in your case, such as 30 seconds or 1 minute.
It depends on the size of your data set of course.
Planner 5.3 will support out-of-the-box construction heuristics.
If time is really short, you might you use a construction heuristic and 
no tabu search or SA at all (although I 'd still recommend to do a few 
seconds of TS or SA anyway).

Also, you probably don't want more Planners running at the same time 
than your numberOfCpuCores - 1.
In that situation you 'll want to queue the planning jobs: there's no 
jbpm-planner integration yet that does that for you yet, but patches 
(pull requests) are welcome ;)
