[gecode-users] Combining of LDSB with Branch and Bound algorithm.

[Bouchene Sabrina]

Hi,I have two questions please:
1- I want to know the theoretical principle of LDSB for symmetry    breaking. 

2- if in an algorithm i would combine a branch and bound  algorithm with the use of the LDSB layer for symmetry reduction ( declaration of symmetries), so how the solver (algorithm) works ? Can someone explain to me the sequential steps of the execution of the set (Branch and bound, LDSB).
Thank you in advance.
Cordially.
