Chaos particle swarm optimization algorithm to match theoretical variogram automatically. Computer Engineering and Applications, 2012, (4) 37-39. 48 : Abstract:Matching the parameter of theoretical model of variogram is one of the specific basic content in geostatistics. Aiming at the disadvantages of conventional used methods in match theoretical variogram, in order to match theoretical variogram automatically, based on the quick convergence of Chaos Particle Swarm Optimization (CPSO)algorithm used in solving nonlinear programming problems, and ergodicity, global optimization of chaos, a new match method of theoretical variogram is performed. Spherical model, which is transformed into minimum problem, is used in the experiment. CPSO is used to find the satisfactory fitness value. Simulations show that the new algorithm has powerful optimizing ability, higher precision, and can automatically match the theoretical variogram effectively. Key words: geostatisti
