Determination of the Heat Flux in the Process of Solidification by Applying the Ant Colony Optimization Algorithm

Abstract

The paper presents an application of Ant Colony Optimization algorithm as a partof procedure for solving the inverse solidification problem. Investigated task consists in recon-struction of the boundary condition (heat flux) on the basis of temperature measurements inselected points of the cast. First step of the method is based on the finite difference method withapplication of the generalized alternating phase truncation method and serves for solving theappropriate direct solidification problem. In the second step some functional representing thecrucial part of the procedure is minimized with the aid of Ant Colony Optimization algorithm.
