Problems solved by technology
[0003] 1. At present, lottery systems on the market generally use simple lottery algorithms to generate random serial numbers. These lottery algorithms generate random serial numbers. There are rules to follow. For example, numbers within a certain range are often arranged in the front or back. The organizers are unaware that the seemingly randomly generated lottery numbers are actually not completely random
[0004] 2. The technical key of the lottery system is to ensure that the lottery process is fair and just, and the lottery results are credible. However, the existing lottery system does not have the verification function of the lottery results. Users who participate in the lottery can only passively accept the lottery results. The results of the lottery are doubtful, and there is no credible way to verify the result of the lottery to verify whether the order of the lottery is generated normally without being inserted

The invention discloses a random lottery and lottery result verification method and system based on interval grouping, and the method comprises the steps: S1, carrying out random sampling of a randomly sorted user number array through a negative hypergeometric random variable sampling algorithm, and obtaining a plurality of interval groups; S2, generating a corresponding random lottery serial number for each element in each interval group by using a Knuth-Shuffle algorithm; and S3, according to the lottery result verification request of the user, verifying whether the user number of the user participates in the random lottery process through an interpolation method of a Lagrange interpolation polynomial, and feeding back a verification result. Random sampling is performed on the user number array by using the negative hypergeometric random variable sampling algorithm and the Knuth-Shuffle algorithm, the lottery serial number is generated, the generation randomness of the lottery serial number is ensured, in addition, whether the user number participates in the random lottery process or not is verified through the interpolation method of the Lagrange interpolation polynomial. And the credibility of the lottery result is improved.
Description
technical field [0001] The invention relates to the technical field of number lottery, in particular to a random number lottery based on interval grouping and a method and system for verifying lottery results. Background technique [0002] In order to balance the relationship between supply and demand, lottery has been widely used in the fields of buying houses and cars. Lottery, that is, the process in which the lottery system uses the preset lottery algorithm to generate random numbers, but the existing random lottery method has the following two problems: [0003] 1. At present, lottery systems on the market generally use simple lottery algorithms to generate random serial numbers. These lottery algorithms generate random serial numbers. There are rules to follow. For example, numbers within a certain range are often arranged in the front or back. The organizers are unaware that the seemingly randomly generated lottery numbers are actually not completely random. [0004...
