Improved Particle Swarm Optimization Algorithm of Inverse Heat Conduction

Inverse Heat Conduction Problem (IHCP) has the characteristics of non-linearity, ill-posed ness and heavy computation, because of which, there haven't been any theories or algorithms with broad application scope to solve it yet. In this paper, we use standard Particle Swarm Optimization (PSO) algorithm to solve fine-mesh 2 Dimensions (2D) IHCP. The experimental data shows that the standard PSO algorithm is not suitable for solving fine-mesh 2D IHCP. Considering the particular application fine-mesh 2D IHCP, the paper gives an improved strategy for the standard PSO algorithm. Results show that the improved PSO algorithm has a great improve in global search capability and solution precision.
