Functions

template<class T >
T * Gecode::bab (T *s, const Search::Options &o=Search::Options::def)
 Perform depth-first branch-and-bound search for subclass T of space s and options o.
template<class T >
T * Gecode::restart (T *s, const Search::Options &o=Search::Options::def)
 Perform depth-first restart best solution search for subclass T of space s and options o.

Detailed Description

Defines search engines. All search engines support recomputation. The behaviour of recomputation is controlled by a passing a search option object (see the class Gecode::Search::Options).

Requires

#include <gecode/search.hh>

Function Documentation

template<class T >
T * Gecode::bab ( T *  s,
const Search::Options &  o = Search::Options::def 
)

Perform depth-first branch-and-bound search for subclass T of space s and options o.

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.

template<class T >
T * Gecode::restart ( T *  s,
const Search::Options &  o = Search::Options::def 
)

Perform depth-first restart best solution search for subclass T of space s and options o.

Additionally, s must implement a member function

virtual void constrain(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.
