Texture decomposition into Gauss-shaped functions: classical and genetic algorithm methods

The results of decomposition of texture function into Gauss-shaped components are presented. Such the decomposition is useful in many applications, especially if one is directly interested in participation of different texture components, corresponding to given crystal orientations (ideal orientations). Texture presentation by Gauss-shaped components enables also in many cases the simplification of data treatment and important reduction of computer time and memory. Two methods of decomposition are presented: the classical one (deterministic) and that based on genetic algorithm method. The quality of both methods is compared. urce code of computer program for classical texture decomposition is available from the authors.
