before

fun <V, F> DistributedConfigScope<V, F>.before(beforeEvolution: suspend DistributedEvolveScope<V, F>.() -> Unit)

Callback before evolution process which will be invoked if GA.iteration is 0.

Example:

// init DistributedGA
dGA(
    // configure common factory, fitnessFunction, population name and children (if already exist)
) {
    // set ga's configuration here (adding children)

    before { (this = DistributedEvolveScope)
        println("GA STARTED, initial iteration is $iteration")
    }
}
