Abstract

This paper presents a method to solve the problem of natural crack shape reconstruction from eddy current testing signals by means of hybrid genetic - tabu search algorithm (GATS). In order to evaluate the efficiency on solving crack shape inversion problem, hybrid GA-TS algorithm is compared with some heuristic algorithms such as particles swarm optimization, ant colony optimization and simple genetic algorithm. The reconstructed results verify the efficiency of neural network based forward model and the promising of hybrid GA-TS algorithm in crack shape inversion.
