Abstract
In this paper, we give an O(n·log n+m)-time algorithm to solve the problem of finding a smallest set of edges whose addition 4-vertex-connects an undirected graph, where n and m are the number of vertices and edges in the input graph, respectively. We also show a formula to compute this smallest number in O(n·α(n,n)+m) time, where α is the inverse of the Ackermann function.
