stop solving after given number of found solutions #16

Closed GoogleCodeExporter closed 9 years ago

As far as i can see, the exposed stopping criteria for 
solver.minimize/maximize are time, gap and absgap. I suggest to add a 
parameter like "nsol" as the maximum number of solutions, after that solving 
stops. Default: -1.

Excerpt from the default parameters of scip:

# solving stops, if the given number of solutions were found (-1: no limit)
# [type: int, range: [-1,2147483647], default: -1]
limits/solutions = -1

For example, nsol=1 would halt the optimization process after the first 
feasible point has been found. That's good for debugging, etc.
