Detailed Description

template<class T, template< class > class E = DFS>
class Gecode::PBS< T, E >

Meta engine using a portfolio of search engines.

The engine will run a portfolio with a number of assets as defined by the options o. The engine supports parallel execution of assets by using the number of threads as defined by the options.

The class T can implement member functions

 virtual bool master(const MetaInfo& mi)

and

 virtual bool slave(const MetaInfo& mi)

When the assets are created, these functions are executed. For more details, consult "Modeling and Programming with Gecode".
