[gecode-users] Stopping Gecode Engine gracefully

[Guido Tack]

Hi,

you can implement your own Stop object by inheriting from Search::Stop.  If you add it to the options of your search engine, the engine periodically calls its stop function.  Simply return true there to stop the search.

Gecode will always use all the heap it can get if it needs it, the limits in memory-config.hpp only affect in what chunks heap memory is allocated.  If you have memory problems, you should try different recomputation parameters (parameters c_d and a_d in the search options).

Cheers,
	Guido

I know it can be stopped by setting time limit, node limit etc. But I want to stop engine at any time and collect the result until that point. Do I overload the run method to get access to Engine or is there another way?
