This paper presents an efficient fully dynamic graph algorithm for maintaining the transitive closure of a directed graph. The algorithm updates the adjacency matrix of the transitive closure with each update to the graph; hence, each reachability query of the form ''Is there a directed path from i
The P 4 -tidy graphs were introduced by I. Rusu to generalize some already known classes of graphs with few induced P 4 (cographs, P 4 -sparse graphs, P 4 -lite graphs). Here, we propose an extension of R. Lin and S. Olariu's work (1994. J. Parallel Distributed Computing 22, 26 36.) on cographs, usi
