Abstract

The invention discloses a general distributed graph processing method and system based on reinforcement learning. The method includes: defining a distributed data processing center based on a graph theory to form a distributed graph; utilizing a preset graph cutting model and a preset graph processing model to cut the distributed graph by utilizing a reinforcement learning mode based on a preset constraint condition; allocating a learning automaton to each vertex; finding the most suitable data processing center for the vertex through training, wherein the possibility of each vertex in all data processing centers obeys certain probability distribution, the whole system comprises five steps of action selection, vertex migration, score calculation, enhanced signal calculation and probabilityupdating in each iteration process, and the iteration is judged to be ended when the maximum iteration frequency is reached or the constraint condition is converged. The distributed graph processingmodel formed by the universal distributed graph processing method provided by the invention is a universal distributed graph model, and only different score calculation schemes and different weight vectors need to be designed for different optimization targets.

Description

technical field [0001] The invention relates to the field of large-scale graph segmentation processing, in particular to a general distributed graph processing method and system based on reinforcement learning. Background technique [0002] In order to efficiently process large-scale graphs, it is usually necessary to partition the graph so that the partitioned subgraphs can be processed in parallel. There are currently several classic models for large-scale graph segmentation: [0003] Heuristic model. The traditional mainstream large-scale graph processing systems Pregel and PowerGraph all use heuristic segmentation algorithms. The default partition method of Pregel is to achieve the optimization goal of enhancing the locality of the partition and reducing the network traffic between computing nodes by performing a modulo operation on the Hash value of the vertex id. By default, PowerGraph adopts the greedy point segmentation method. For a newly added edge, if a vertex o...
