Evaluation of stochastic functions incrementally\nimprove the estimation of the mean and variance of fitness\nvalues at almost no additional cost. Evaluation functions for\ngene repair handle error-correcting decoders. Third, timing and\ncounting functions for profiling the algorithm pipeline are\nprovided to assess bottlenecks in the algorithms. Fourth, a\nsmall collection of problem environments for function\noptimization, combinatorial optimization, and grammar-based\ngenetic programming and grammatical evolution is provided for\ntutorial examples. For 'xega''s architecture, see Geyer-Schulz,\nA. (2025) . The methods in the\npackage are described by the following references: Baker, James\nE. (1987, ISBN:978-08058-0158-8), De Jong, Kenneth A.
