On Computing Graph Closures
Given a graph $G$, the closure of $G$ is the graph obtained from $G$ by recursively joining pairs of non-adjacent vertices whose degree sum is at least $n$ until no such pair remains. We give an efficient algorithm to compute the closure using F-heaps. We also define the general closure of a graph and show that computing the general closure is $P$-complete with respect to log space transformations.
