In xegaPopulation: Genetic Population Level Functions

Future apply of R-package future.apply configured for a tasks with heterogenous execution times.

Description

The lapply() function is redefined as as future.apply::future_lapply().

Henrik Bengtsson recommends that the configuration of the parallel/distributed programming environment should be kept outside the package and left to the user. The advantage is that the user may take advantage of all parallel/distributed available backends for the Future API.

Usage

futureLapplyHet(pop, EvalGene, lF)

Arguments

pop	Population of genes.
EvalGene	Function for evaluating a gene.
lF	Local function factory which provides all functions needed in EvalGene.

Details

This configuration has an increased communication and synchronization overhead.

Value

Fitness vector.
