%description
This collection of gene representation-independent mechanisms for
evolutionary and genetic algorithms contains four groups of functions:
First, functions for selecting a gene in a population of genes according
to its fitness value and for adaptive scaling of the fitness values as
well as for performance optimization and measurement offer several
variants for implementing the survival of the fittest. Second, evaluation
functions for deterministic functions avoid recomputation. Evaluation of
stochastic functions incrementally improve the estimation of the mean and
variance of fitness values at almost no additional cost. Evaluation
functions for gene repair handle error-correcting decoders. Third, timing
and counting functions for profiling the algorithm pipeline are provided
to assess bottlenecks in the algorithms. Fourth, a small collection of
problem environments for function optimization, combinatorial
optimization, and grammar-based genetic programming and grammatical
evolution is provided for tutorial examples. The methods in the package
are described by the following references: Baker, James E. (1987,
