- Abstract:

The ant lion optimizer (ALO) reveals such deficiencies as easily relapsing into local optimum and low convergence speed. This paper proposed an improved ALO algorithm with Levy variation and adaptive elite competition mechanism. By carrying out Levy variation to poor individuals, the diversity of population and the global search ability of the algorithm can be increased. Moreover, the adaptive elite competition mechanism that many elites lead the population to search at the same time can improve the convergence speed of the algorithm. To reduce the amount of calculation, the number of the elites competing in parallel will decrease with the increase of iterations. By contrast with other improved optimization algorithms, the test results show that the improved algorithm proposed in this paper has better search precision and convergence speed. Finally, this improved algorithm is applied to identify parameters of silicon single crystal thermal field temperature model and the simulation results prove its excellent ability of parameters identification.
