Given a parallel program represented by a task graph, the objective of a scheduling algorithm is to minimize the overall execution time of the program by properly assigning the nodes of the graph to the processors. This multiprocessor scheduling problem is NP-complete even with simplifying assumptio
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
A parallel algorithm is developed for the f i t time based on Frame's method to compute the characteristic polynomials of chemical graphs. This algorithm can handle all types of graphs: ordinary, weighted, directed, and signed. Our algorithm takes only linear time in the CRCW PRAM model with O(n9) p
