WebIn graph theory and theoretical computer science, the longest path problem is the problem of finding a simple path of maximum length in a given graph. A path is called simple if it does not have any repeated vertices; the length of a path may either be measured by its number of edges, or (in weighted graphs) by the sum of the weights of its edges. WebIn the graph drawing applications of the Coffman–Graham algorithm, the resulting directed acyclic graph may not be the same as the graph being drawn, and in the scheduling applications it may not have an edge for every precedence constraint of the input: in both cases, the transitive reduction removes redundant edges that are not necessary ...
