Method of Gene Expression Programming for Solving Equality Constraint
Pei Wang · Computer Technology and Development · 2011
Gene Expression Programming(GEP) is a new genetic algorithm for function discovery.In differential equation,sometimes hope to find the function that meet equality constraints.In order to reach this goal,algorithm with Lagrange interpolation function is proposed which makes the function fulfill the requirement of constraints.Size scale is proposed to amplify or lessen the target value in order to improve the evolutionary efficiency and precision of gene expression programming algorithm.As a result,the evolution distance of GEP algorithm shortens and the evolutionary efficiency increases.Finally,numerical experiments are performed and the results show that the method is feasible.
