Abstract

The invention relates to the technical field of graph computing, and discloses a graph traversal memory access optimization method, system and electronic equipment based on a Hybrid storage format. The optimization method randomly generates an adjacency matrix AM for storing graph data; and performs graph data processing on the adjacency matrix AM to generate a matrix hybrid in a new storage format; finally, according to the generated matrix hybrid in a new storage format, BFS search is completed Breadth-first search on a graph. The present invention adopts a matrix hybrid in a new storage format to store graph data, and effectively solves problems such as excessive memory consumption or array overflow in the graph traversal algorithm of existing various stored graph data structures.

Description

technical field [0001] The present invention relates to the technical field of graph computing, and more particularly, to a graph traversal memory retrieval optimization method, system and electronic device based on a Hybrid storage format. Background technique [0002] Graph is a very important data structure. In reality, many problems can be abstracted and reduced into graph computing problems before further processing. In practice, full graphs are rarely used, and applications of dense graphs are relatively rare. In reality, most graphs are sparse graphs, especially the graphs involved in large-scale graph computation are extremely sparse. [0003] Breadth-First Search (BFS) is a classical algorithm for graph computation, and it is also a graph computation method for blind search. It does not consider the possible location of the result, and searches the entire graph thoroughly, with the purpose of starting from a certain location. A point starts the expansion of the sys...
