[gecode-users] How to create distributing strategies

It's called "branching".

> 2. Will (or does) gecode implements this distributor?

Not yet. In fact, except for the cumulatives constraint, we don't have any 
propagators for scheduling constraints yet, and hence haven't implemented 
branchings for scheduling either.

As long as the tutorial documentation is not available, you will have to take 
an existing branching together with the reference documentation and figure 
out how it works. The current branchings for integer variables can be found 
in the files int/branch.* and int/branch/*. Please have a look at these files 
and their documentation, and if anything is not clear to you, feel free to 
use the mailing list for any questions that come up.

Cheers,
	Guido
