Hi,
If you are using a Gecode Space in a concurrent setting, there are a
couple of things that you must observe.
First of all, a Space is not reentrant. Thus you must serialize all
accesses to the Space object.
Secondly, if you want to manipulate two different Spaces concurrently,
you must make sure that they do not share any data structures. This is
done by passing false as the share argument when cloning a Space.
Cheers,
Mikael
