Method Detail

cost

protected double cost(Target target,
          Unit unit,
          FeatureDefinition weights,
          WeightFunc[] weightFunctions)

Compute the goodness-of-fit of a given unit for a given target

Overrides:

cost in class FFRTargetCostFunction

Parameters:

target - target unit

unit - candidate unit

weights - FeatureDefinition

weightFunctions - array of WeightFunctions

Returns:

a non-negative number; smaller values mean better fit, i.e. smaller cost.

Throws:

IllegalArgumentException - if featureName not available in featureDefinition

featureCost

protected double featureCost(Target target,
                 Unit unit,
                 String featureName,
                 FeatureDefinition weights,
                 WeightFunc[] weightFunctions)

Compute the goodness-of-fit between given unit and given target for a given feature

Overrides:

featureCost in class FFRTargetCostFunction

Parameters:

target - target unit

unit - candidate unit

featureName - feature name

weights - FeatureDefinition

weightFunctions - array of WeightFunctions

Returns:

a non-negative number; smaller values mean better fit, i.e. smaller cost.

Throws:

IllegalArgumentException - if featureName not available in featureDefinition
