The view238 application is a simple tool for graphically displaying STEP-NC toolpaths. It is a Java application that reads AP-238 XML data using the DOM inferface, then finds and display the toolpaths within. At present, only polylines, and circular

Implementation of Edmonds Karp algorithm that calculates maxFlow of graph. Input: For each test case, the first line contains the number of vertices (n) and the number of arcs (m). Then, there exist m lines, one for each arc (source vertex, endin

A Petri net (also known as a place/transition net or P/T net) is one of several mathematical modeling languages for the descr iption of distributed systems. A Petri net is a directed bipartite graph, in which the nodes represent transitions (i.e. eve
