public class Utilitarian
extends BimatrixEquilibriumSolver

Finds the maximum utilitarian value joint action and retuns a detemrinistic strategy respecting it. The utilitarian value is the sum of the two player's payoffs for a cell. If there are multiple maximums, the first is always used.

computeRowStrategy

public double[] computeRowStrategy(double[][] rowPayoff,
                                   double[][] colPayoff)

Description copied from class: BimatrixEquilibriumSolver

Computes and returns the row player strategy for the given bimatrix game. The strategy is represented as a double array where a[i] is the probability of action i being selected.

Specified by:

computeRowStrategy in class BimatrixEquilibriumSolver

Parameters:

rowPayoff - the row player payoffs.

colPayoff - the column player payoffs.

Returns:

the row player strategy.

computeColStrategy

public double[] computeColStrategy(double[][] rowPayoff,
                                   double[][] colPayoff)

Description copied from class: BimatrixEquilibriumSolver

Computes and returns the column player strategy for the given bimatrix game. The strategy is represented as a double array where a[i] is the probability of action i being selected.

Specified by:

computeColStrategy in class BimatrixEquilibriumSolver

Parameters:

rowPayoff - the row player payoffs.

colPayoff - the column player payoffs.

Returns:

the column player strategy.
