摘要： A Gene Expression Programming method evolves a population of chromosomes which are arrays of integer index references to genes including operand and operator genes. The mathematical expressions are encoded in the chromosomes according to linear Polish notation, according to which expression trees representing mathematical expression encoded in the chromosomes are developed in a depth-first manner from the sequence of genes in each chromosome. This type of Polish notation makes it more likely that sub-expressions that contribute to fitness will survive evolutionary operations which can be performed at a low computational cost on array chromosomes. Additionally subexpressions or the mathematical structure of subexpressions which are assumed to contribute significantly to fitness based on the frequency of their appearance in elite members are protected from alteration by evolutionary operations, by representing each such mathematical structure by a single derived gene while the evolutionary operations are performed.
