An R package for optimization using genetic algorithms.
The package provides a flexible general-purpose set of tools
for implementing genetic algorithms search in both the
continuous and discrete case, whether constrained or not. Users
can easily define their own objective function depending on the
problem at hand. Several genetic operators are available and
can be combined to explore the best settings for the current
task. Furthermore, users can define new genetic operators and
easily evaluate their performances.
