Abstract: Genetic algorithms are an important data mining classification mining algorithms.The simple genetic algorithm has great randomness，higher error rate.It is difficult to meet the needs of data mining.To this end，this paper presents a genetic algorithm and the Apriori-based classification mining algorithms——GAA.From the code design，fitness function，genetic operators to discuss the design and analysis，an instance is adopted to complete the application.The results show that the algorithm in few algebraic cases，can effectively improve the classification accuracy，and has a certain practical value.
