DETERMINATION OF STABILITY-CONSTANTS OF COMPLEX BY USING NUMERIC GENETIC ALGORITHM

A novel global optimal method - numeric genetic algorithm (NGA) is proposed in this paper. NGA can deal with the optimization of continuous variables. NGA can also find global optimal in the presence of many local optimal and is especially suitable to deal with complicated nonlinear problem. Individual and population are varied by genetic operations to gradually adapt the environment. Besides crossover and mutation, a new genetic operation-memory is proposed in this paper to shorten the calculating time. The stability constants of trichlorosalicylic acid and its complexes of copper and iron have been calculated by using NGA.
