Abstract: Based on the principle of XML configuration, we gave a greedy strategy algorithm and tested the algorithm. Aiming at the problems existing in the testing process, we optimized the algorithm to obtain the multidimensional extended greedy algorithm, and carried out comparative experiments on different algorithms. The experimental results show that the algorithm has the advantages of high reliability, fast execution and comprehensive coverage, and the more data are run, the more accurate the results are.

Key words: greedy strategy algorithm, multidimension extended greedy algorithm, data mining
