The importance and computational precision of different points is not same on the practical variogram curve in geostatistics. For this reason, in this paper, a method is suggested to estimate the variogram parameters such as range, nugget and sill at the same time by using the accelerating genetic algorithm(AGA) developed by the authors, under the weighted least square criterion of errors between practical variogram values and theoretical model computational values. The results of the application example show that AGA is convenient, general and high precision. AGA can be widely applied to different spatial optimal problems in geostatistics
