[gecode-users] BAB implementation

[aqwzsxaqwzsx at orange.fr]

Hi,
 
Definitively not a homework. I have to make a technical choice to
solve a planification problem with task/resources/scheduling.
A * will be homogeneous with the rest of the software
but CSP with a BAB engine seems clearly more appropriate to me.
It has been proved in 1984 by Nau/Kumar/Kanal that A* is a special
case of a general BAB formulation and I don't see any reason why
it would not be the case with Gecode, but i was asking some
advice to decide !
Moreover, i will maybe have some questions about coding rules in gecode relative to embedded system.

Hi, I think you will have to do some reading. Smells like homework to me. Christian

Hi all,
 
This is maybe a general question about the B&B and the A* algorithm, But I was wondering what was the advantage, force, weakness of the Gecode BAB engine over a A*. 

Thanks
