Abstract Some available multimodal optimization algorithms are analyzed and the faults of them are pointed out. Based on their same features that they all have fine search effect to functions with equivalence peaks, the peaks poised strategy is proposed. Then a new Multimodal Immune Algorithm (MIA) with mechanisms of antibody evolution in immune system and conventional gradient evolution is designed. The implementations of peaks poised strategy and main evolution operators are given, the algorithm's operating mechanisms, complete convergence and computation complicacy are analyzed. The simulation experiments are performed and the results testify that MIA has availability on solving multimodal optimization problems, especially for functions with nonequivalence peaks, complete convergence and quickly convergence ability.
