%description
Flexible general-purpose toolbox implementing genetic algorithms (GAs) for
stochastic optimisation. Binary, real-valued, and permutation
representations are available to optimize a fitness function, i.e. a
function provided by users depending on their objective function. 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. Local search using
general-purpose optimisation algorithms can be applied stochastically to
exploit interesting regions. GAs can be run sequentially or in parallel,
using an explicit master-slave parallelisation or a coarse-grain islands
approach. For more details see Scrucca (2013) <doi:10.18637/jss.v053.i04>
and Scrucca (2017) <doi:10.32614/RJ-2017-008>.
