This paper analyzed the Logistic map, Tent map, ICMIC map, Bernouilli shift map, Chebyshev map and Sine map. Compared the chaotic search effect of different one-dimensional chaotic map in solving nonlinear optimization problems. The global optimization ability, convergence rate and solution accuracy of the six kinds of maps were tested using four kinds of two-dimensional function. Compared the performance of their optimization by simulation. Obtained the performance comparison conclusion of the six kinds of maps in convergence rate and solution accuracy.
