The vertices are numbered 1 through n. Next, n − 1 lines describing the initial tree follow.
WebIn graph theory, a cop-win graph is an undirected graph on which the pursuer (cop) can always win a pursuit–evasion game against a robber, with the players taking alternating turns in which they can choose to move along an edge of a graph or stay put, until the cop lands on the robber's vertex. Finite cop-win graphs are also called dismantlable graphs … flotherm 2021 破解Webjan graphs. By replacing each undirected edge by two directed edges of opposite directions, the associated directed Ramanujan graph has the same eigenvalues. Corollary 1 yields an upper bound within a factor of 4 of the bound for the undirected case.
