Abstract

Linear multiplicative congruential method(LMCM) random number generators are widely utilized in car registration lottery. To improve the statistical qualities of the code distribution for purchasing lottery of application and lucky random number sequence, according to the application demand, this paper designed a new linear multiplicative congruential algorithm, which based on the concept of uniformly distribution. In the new algorithm, with the original method of LMCM generator of modulus as the foundation, the random number produced through the same seeds uniform distributed. Due to implementation of the segmentation algorithm, the generation of random numbers would not increase obviously in the amount of calculation, which could satisfy the demands of car registration lottery. Statistical test results show that the proposed algorithm for statistical quality improvement of random sequences is significant. At the same time, the algorithm has been successfully applied to car lottery system in Guiyang specific areas, which show a good application population. Therefore, the method can be as a new random number sampling algorithm.
