Optimizing and matching bitstrings

Strings of bits (bitstrings) are a common first-order representation in the design and preliminary investigation of computational intelligence algorithms given (1) the ease in mapping the strings to arbitrary domains (such as real numbers), and (2) in terms of mathematical analysis. This work considers the use of bitstrings in the context of the clonal expansion and antigenic selection in a general clonal selection algorithm and provides a general review of mutation-based optimization (genetic algorithms) and bit-string matching (classifier systems and negative selection).
