org.apache.spark.mllib.clustering.KMeansModel.computeCost()

rinde.sim.pdptw.common.ObjectiveFunction.computeCost()

Computes the cost (i.e. objective value) of the specified {@link StatisticsDTO}. @param stats The {@link StatisticsDTO} to inspect. @return The cost.

rinde.sim.pdptw.gendreau06.Gendreau06ObjectiveFunction.computeCost()

Computes the cost according to the definition of the paper: the cost function used throughout this work is to minimize a weighted sum of three different criteria: total travel time, sum of lateness over all pick-up and delivery locations and sum of overtime over all vehicles. The function is defined as: sum(Tk) + alpha sum(max(0,tv-lv)) + beta sum(max(0,tk-l0)) Where: Tk is the total travel time on route Rk, alpha and beta are weighting parameters which were set to 1 in the paper. The definition of lateness: max(0,lateness) is commonly referred to as tardiness. All times are expressed in minutes.

    final double cost = objFunc.computeCost(stats);


    final double cost0 = objFunc.computeCost(Solvers.computeStats(
        state.withSingleVehicle(0),
        ImmutableList.of(routes.get(0))));
    final double cost1 = objFunc.computeCost(Solvers.computeStats(
        state.withSingleVehicle(1),
        ImmutableList.of(routes.get(1))));
    assertEquals(cost, cost0 + cost1, 0.001);
  }
