public interface ValueFunction

An interface for algorithms that can return the value for states.

Author:

James MacGlashan.

Method Summary

Modifier and Type	Method and Description
double	value(State s) Returns the value function evaluation of the given state.

Method Detail

value

double value(State s)

Returns the value function evaluation of the given state. If the value is not stored, then the default value specified by the ValueFunctionInitialization object of this class is returned.

Parameters:

s - the state to evaluate.

Returns:

the value function evaluation of the given state.
