OpenStudio R Packages

This code is designed to work with the OpenStudio Server and may not be appropriate for solo use. It contains modified versions of existing R packages to fit the parallelization needs of the OS-Server. In most cases, the existing parallelization is replaced with one that takes an externally defined cluster object and then uses the clusterApplyLB or parApplyLB method in R::Parallel.

Available Algorithms

These modified algorithms are available from the following R packages:

nsga2R

  • NSGA2 (Nondominated Sorting Genetic Algorithm 2) multi-objective optimization
  • SPEA2 (Strength Pareto Evolutionary Algorithm 2) multi-objective optimization

GA

  • GA (optimization using genetic algorithms - single-objective optimization)
  • GAIslands (optimization using Islanding genetic algorithms - single-objective optimization)

hydroPSO

  • PSO (Particle Swarm Optimization) single-objective optimization
