+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.")
