One of the most fundamental problems in … WebMay 1, 2024 · Reachability preserving compression is a technique that compress a directed graph 1 with respect to a certain class of queries, and only the information related to the query class is retained in the compressed graph. The query evaluation methods on the original graph can be directly applied to the compressed graph without decompression.
