For a DAG, the longest path from a source vertex to all other vertices can be obtained by running the shortest-path algorithm on −G. Similarly, for each vertex v in a given DAG, the length of the longest path ending at v may be obtained by the following steps: Find a topological ordering of the given DAG.
The longest uncrossed (or nonintersecting) knight's path is a mathematical problem involving a knight on the standard 8×8 chessboard or, more generally, on a square n×n board. The problem is to find the longest path the knight can take on the given board, such that the path does not intersect itself.
A three-dimensional hypercube graph showing a Hamiltonian path in red, and a longest induced path in bold black. In graph theory, a path in a graph is a finite or infinite sequence of edges which joins a sequence of vertices which, by most definitions, are all distinct (and since the vertices are distinct, so are the edges).
In graph theory terminology, this is called finding the longest possible induced path in a hypercube; it can be viewed as a special case of the induced subgraph isomorphism problem. There is a similar problem of finding long induced cycles in hypercubes, called the coil-in-the-box problem.
Lolicon to Pamela Levy - no path under 10 steps, although the return path is only 4 steps. Lolicon → Eat Me, Drink Me → David Lynch → Fairfield, Iowa → Pamela Levy Lolicon → John Reid, Baron Reid of Cardowan → United Kingdom → Culture of the United Kingdom → Pamela (disambiguation) → Pamela (name) → Pamela Levy .
Longest path problem; Addition-chain exponentiation; Least-cost airline fare. Using online flight search, we will frequently find that the cheapest flight from airport A to airport B involves a single connection through airport C, but the cheapest flight from airport A to airport C involves a connection through some other airport D.

An induced path of length four in a cube.Finding the longest induced path in a hypercube is known as the snake-in-the-box problem.. In the mathematical area of graph theory, an induced path in an undirected graph G is a path that is an induced subgraph of G.
