[Cbc] maxSolutions that meet all constraints

[James Vance]

hello,

When working with the maxSolutions parameter (say maxSolutions=3), CBC
often returns solutions that don't meet every constraint. If I let the
solver run without specifying maxSolutions the solution it returns meet
every constraint.

Can anyone explain this phenomenon and is there a way to check constraints
before returning solutions?

Thanks,

James
