Interface RewardFunction

  • All Implemented Interfaces:
    java.io.Serializable 
    @FunctionalInterface() 
public interface RewardFunction
 implements Serializable

    Functional interface for defining reward functions on CTMC states. A reward function maps a state vector and network structure to a scalar reward value. This interface is used for CTMC reward computation via value iteration. Example usage: 

    // Queue length reward
RewardFunction qlenReward = (state, sn) -> state.get(0, 1);

// Throughput reward
RewardFunction tputReward = (state, sn) -> {
    double n = state.get(0, 1);
    return n > 0 ? n * sn.rates.get(1, 0) / n : 0;
};

         abstract double compute(Matrix state, NetworkStruct sn)

        Compute the reward value for a given state.

        Parameters:
        state - The state vector (row from stateSpaceAggr matrix) Format: [n_{1,1}, n_{1,2}, ...
        sn - The NetworkStruct providing access to rates, parameters, etc.
        Returns:

        The reward value for this state
