Detailed Description

template<class T>
class Gecode::BAB< T >

Depth-first branch-and-bound search engine.

Additionally, s must implement a member function

virtual void constrain(const T& t) 

Whenever exploration requires to add a constraint to the space c currently being explored, the engine executes c.constrain(t) where t is the so-far best solution.
