    On the power of bfs to determine a graph’s diameter

    Abstract. Recently considerable effort has been spent on showing that Lexicographic Breadth First Search (LBFS) can be used to determine a tight bound on the diameter of graphs from various restricted classes. In this paper, we show that in some cases, the full power of LBFS is not required and that other variations of Breadth First Search (BFS) suffice. The restricted graph classes that are amenable to this approach all have a small constant upper bound on the maximum sized cycle that may appear as an induced subgraph. We show that on graphs that have no induced cycle of size greater than k, BFS finds an estimate of the diameter that is no worse than diam(G) −⌊k/2⌋−2.

    We discuss the physics goals and rationale for a detector to study Beauty and Charm decays in the forward direction at the Fermilab Tevatron Collider. We then describe the BTeV detector which has been designed to achieve these goals and present its physics reach based on extensive simulation. We conclude by comparing BTeV to other experiments designed to explore similar topics
