Abstract :
This paper presents a method to solve the problem of natural crack shape reconstruction from eddy current testing signals by means of imperialist competitive algorithm (ICA). ICA is a new meta-heuristic optimization and stochastic search strategy which is inspired from socio-political phenomenon of imperialistic competition. In order to evaluate the efficiency on solving crack shape inversion problem, ICA is compared with some heuristic algorithms such as genetic algorithm, particles swarm optimization and ant colony optimization. The reconstructed results verified the efficiency of neural network based forward model and the promising of imperialist competitive algorithm in crack shape inversion.
