Abstract: A novel algorithm, called the self-adaptive chaos quantum clonal algorithms-SCQA, is proposed to avoid premature convergence. By adopting the quantum bit as a representation, SCQA uses the Logistic Sequence to control the mutation size and Chaos Mutation Operator to control the clonal selection. Simulations with function optimization problems show that SCQA performs well in terms of the quality of solution and computational cost,where the standard deviation is up to 10-7 and the number of the mean generations is less than 10.
