## Abstract A directed cycle __C__ of a digraph __D__ is extendable if there exists a directed cycle __C__′ in __D__ that contains all vertices of __C__ and an additional one. In 1989, Hendry defined a digraph __D__ to be cycle extendable if it contains a directed cycle and every non‐Hamiltonian di

✦ Synopsis
Let s(n) be the threshold for which each directed path of order smaller than s ( n ) is extendible from one of its endpoints in some tournament T,. It is shown that s(n) is asymptotic to 3n/4, with an error term at most 3 for infinitely many n. There are six tournaments with s ( n ) = n.

We present an O n algorithm for finding a specified oriented path of order at Ž 2 . least n in a tournament of order n. Using this algorithm, we present an O n algorithm that finds a specified oriented path from a given vertex if one exists.
We prove that with three exceptions, every tournament of order n contains each oriented path of order n. The exceptions are the antidirected paths in the 3-cycle, in the regular tournament on 5 vertices, and in the Paley tournament on 7 vertices. ## 2000 Academic Press Tournaments are very rich st
## Abstract An in‐tournament is an oriented graph such that the negative neighborhood of every vertex induces a tournament. Let __m__ = 4 or __m__ = 5 and let __D__ be a strongly connected in‐tournament of order ${{n}}\geq {{2}}{{m}}-{{2}}$ such that each arc belongs to a directed path of order at
Efficient performance tuning of parallel programs is often hard. Optimization is often done when the program is written as a last effort to increase the performance. With sequential programs each (executed) code segment will affect the completion time. In the case of a parallel program executed on a
