Multiple representations (binary, real-coded,\npermutation, and derivation-tree), a rich collection of genetic\noperators, as well as an extended processing pipeline are\nprovided for genetic algorithms (Goldberg, D. E. (1989,\nISBN:0-201-15767-5)), differential evolution (Price, Kenneth\nV., Storn, Rainer M. and Lampinen, Jouni A. (2005)\n), simulated annealing (Aarts, E.,\nand Korst, J.

All algorithms reuse basic\nadaptive mechanisms for performance optimization. For 'xega''s\narchitecture, see Geyer-Schulz, A. (2025)\n. Sequential or parallel execution\nwith master-slave pattern (on multi-core machines, local\nclusters, and high-performance computing environments) is\navailable for all algorithms.
