Method Detail

recombine

public final io.vavr.Tuple2<S,S> recombine(S solution1,
                                           S solution2)

Specified by:

recombine in interface Recombination<S extends Solution<io.vavr.collection.Array<T>>>

swap

protected final <R> io.vavr.Tuple2<io.vavr.collection.Array<R>,io.vavr.collection.Array<R>> swap(io.vavr.collection.Array<R> representation1,
                                                                                                 io.vavr.collection.Array<R> representation2,
                                                                                                 int index)

Swaps the representations at the given index.

This method purpose is to allow efficient unboxing in case of representations of primitives. Subclasses can then cast the given representation in the corresponding fastutil collection.

Parameters:

representation1 - the first representation

representation2 - the second representation

index - the index at which swapping should occur

isMemoized

public boolean isMemoized()
