inline suspend fun <V, F> PanmicticEvolveScope<V, F>.selectionWithIndex(parallelismLimit: Int, crossinline selection: (index: Int, source: Array<Chromosome<V, F>>, random: Random) -> Chromosome<V, F>)

Performs a selection step for population in PanmicticGA. Suitable for selection mechanisms where behavior depends on indices. For example: selTournament
