Solving the Material Interface Reconstruction Problem using Genetic Programming

Abstract: This paper develops enhanced material interface reconstruction techniques using genetic programming. Material interface reconstruction is the attempt to recreate high resolution material placement in computational meshes given only the percentages of materials at the coarser level of cells in the mesh. Previous techniques have been designed to create either accurate percentages or smooth interfaces, but not both. This paper suggests evolved modifications to known techniques as well as novel methods to combine the two goals of material interface reconstruction.
