Shortest Path Problem -- from Wolfram MathWorld

WebFeb 8, 2024 · Here we show that the Path problem for graphs is in P, the problem of determining if a directed graph G has an s-t path (a way of picking vertices starting at s and ending at t). WebWe will prove that G has a Hamiltonian path by using the following theorem, known as Dirac's theorem: Dirac's Theorem: Let G be a simple graph with n vertices, where n>=3. If every vertex in G has degree at least n/2, then G has a Hamiltonian cycle. In our case, G has 2k+1 vertices, so n=2k+1. Since G is k-regular, each vertex in G has degree k.
