IFOA: an improved forest algorithm for continuous nonlinear optimisation

摘要

Forest optimisation algorithm (FOA) is a new evolutionary optimisation algorithm which is inspired by seed dispersal procedure in the forests, suitable for continuous nonlinear optimisation problems. In this paper, an improved forest optimisation algorithm (IFOA) is introduced to improve convergence speed and the accuracy of FOA, and four improvement strategies which include the greedy strategy, waveform step, preferential treatment of best tree and new-type global seeding are proposed to solve continuous nonlinear optimisation problems better. The capability of IFOA has been investigated through the performance of several experiments on well-known test problems and the results prove that IFOA is able to perform global optimisation effectively with high accuracy and convergence speed.
