摘要: A modified genetic algorithm of multiple selection strategies, crossover strategies and
adaptive operator is constructed, and it is used to estimate the kinetic parameters in
autocatalytic oxidation of cyclohexane. The influences of selection strategy, crossover
strategy and mutation strategy on algorithm performance are discussed.This algorithm with a
specially designed adaptive operator avoids the problem of local optimum usually associated
with using standard genetic algorithm and simplex method. The kinetic parameters obtained
from the modified genetic algorithm are credible and the calculation results using these
parameters agree well with experimental data.Furthermore, a new kinetic model of
cyclohexane autocatalytic oxidation is established and the kinetic parameters are estimated
by using the modified genetic algorithm.
