The post on applying GPU to finding Eulerian path mentioned a stumbling block: partitioning a very specific kind of graph. In general, partitioning is a hard problem, NP-hard actually. The graphs we are dealing with are very specific, though, and may be partitioned in $latex O(|E|)$ time (E - the set of graph edges). Our … Continue reading HashSet, Graph, Cognac
