network	Cream.Network	/// the constraint network ///
return	System

DefaultSolver() public method

Initializes a new instance of the DefaultSolver class. Constructs a branch-and-bound solver for the given network and options. This constructor is equivalent to DefaultSolver(network, options, null).

public DefaultSolver ( Cream.Network network, int options ) : System
network	Cream.Network	/// the constraint network ///
options	int	/// the options for search strategy ///
return	System

DefaultSolver() public method

Initializes a new instance of the DefaultSolver class. Constructs a branch-and-bound solver for the given network, options, and name.

public DefaultSolver ( Cream.Network network, int options, string name ) : System
network	Cream.Network	/// the constraint network ///
options	int	/// the options for search strategy, or Default for default search strategy ///
name	string	/// the name of the solver, or `null` for a default name ///
return	System

DefaultSolver() public method
