In order to verify the performance of the user grouping algorithm, this paper combines the trained MDDQN agent with swap matching search and exhaustive search respectively, and the performance comparison is shown in Fig. The total energy consumption of the MDDQN + Matching search algorithm is very close to the optimal solution obtained by the MDDQN + exhaustive search algorithm. Time complexity of swap matching search algorithm is lower than that of exhaustive search. In general, swap matching search algorithm has lower time complexity and similar performance with exhaustive search algorithm.
