[gecode-users] How control the engine??

[Christian Schulte]

Hi, that's great. Some things can be done in a more elegant way maybe (maybe
using a virtual function and always pass an EndCondition object. this would
be less efficient but nicer).

We are currently preparing 1.0.1 where your patch will not go in. Then let's
see for 1.0.2.
