Genetic algorithms are a general class of search methods that mimic na
tural gene-based optimization mechanisms. Mutation, cross-over and rep
lication operations are performed on strings. When applied to structur
e prediction, each string describes a particular conformation of a pro
tein molecule. There are many ways in which such search methods may be
implemented. Recent results show potential for helping with protein s
tructure prediction, but more data are needed before a complete assess
ment can be made.
