C# Class Cream.LocalSearch

A super class of local search solvers, and also an implementation of a random walk solver. Local search is an iterative procedure. It first finds an initial soluttion, and iteratively make a small change

Public Methods

Method	Description
LocalSearch ( Cream.Network network ) : System	Constructs a random-walk solver for the given network. This constructor is equivalent to `LocalSearch(network, Default, null)`.
LocalSearch ( Cream.Network network, String name ) : System	Constructs a random-walk solver for the given network and name. This constructor is equivalent to `LocalSearch(network, Default, name)`.
LocalSearch ( Cream.Network network, int option ) : System	Constructs a random-walk solver for the given network and option. This constructor is equivalent to `LocalSearch(network, option, null)`.
LocalSearch ( Cream.Network network, int option, String name ) : System	Constructs a random-walk solver for the given network, option, and name.

LocalSearch() public method

Constructs a random-walk solver for the given network. This constructor is equivalent to LocalSearch(network, Default, null).

public LocalSearch ( Cream.Network network ) : System
network	Cream.Network	the constraint network ///
return	System

LocalSearch() public method

Constructs a random-walk solver for the given network and name. This constructor is equivalent to LocalSearch(network, Default, name).

public LocalSearch ( Cream.Network network, String name ) : System
network	Cream.Network	the constraint network ///
name	String	the name of the solver ///
return	System

LocalSearch() public method

Constructs a random-walk solver for the given network and option. This constructor is equivalent to LocalSearch(network, option, null).

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

LocalSearch() public method

Constructs a random-walk solver for the given network, option, and name.

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