WebLets define by f(x) this path length. Longest path starts in subtree of x, passes through x and ends in subtree of x (denoted by red line in image). Lets define by g(x) this path length. If for all nodes x, we take maximum of f(x), g(x), then we can get the diameter. But first, we need to see how we can calculate maximum path length in both cases. Weba. Find the longest path delay from an external circuit input to the positive edge of the clock. b. Find the longest path delay from the positive edge of the clock to the external output. c.

WebDec 27, 2024 · The statement L [s] = [s] means "The longest path ending at node s (i.e., L [s] on the left side of the assignment) is the path only containing node s (i.e., [s] on the right side of the assignment. There are algorithms like Dijkastras algorithm which can be modified to find the longest instead of the shortest path. WebDijkstra’s algorithm step-by-step. This example of Dijkstra’s algorithm finds the shortest distance of all the nodes in the graph from the single / original source node 0.
