Detailed Description

This interface defines common functionalities in all utility solution spaces.

A utility solution space is a solution space in which each solution has an associated value, called "utility".

Author: Radoslaw Szymanek, Thomas Leaute

Parameters

Augments this BasicUtilitySolutionSpace with a new combination of variables values associated with a given utility.

Note: If the corresponding assignment already exists in BasicUtilitySolutionSpace, this method will only modify the corresponding utility value.

Parameters

utility_value	corresponding utility value

Implemented in frodo2.solutionSpaces.hypercube.BasicHypercube< V extends Addable< V >, U extends Serializable >.

◆ changeVariablesOrder()

BasicUtilitySolutionSpace< V, U > frodo2.solutionSpaces.BasicUtilitySolutionSpace< V extends Addable< V >, U extends Serializable >.changeVariablesOrder ( String[] variables_order )

Returns a new BasicUtilitySolutionSpace by changing the order of the variables of this BasicUtilitySolutionSpace.
