Methods

Modifier and Type	Method and Description
double	aggregate(Vector x, Vector y, DoubleDoubleFunction fa, DoubleDoubleFunction fc) Main method that applies fc to x and y component-wise aggregating the results with fa.
double	estimateCost(Vector x, Vector y, DoubleDoubleFunction fa, DoubleDoubleFunction fc) Estimates the cost of using this algorithm to compute the aggregation.
boolean	isValid(Vector x, Vector y, DoubleDoubleFunction fa, DoubleDoubleFunction fc) Returns true iff we can use this algorithm to apply fc to x and y component-wise and aggregate the result using fa.
