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.
