## Abstract An algorithm for computing a linear Chebyshev approximation to a function defined on a finite set of points is presented. The method requires the accuracy of the approximation to be specified, and determines the least degree approximation which achieves this accuracy. The algorithm is b

## Abstract A computably enumerable (c.e.) degree a is called nonbounding, if it bounds no minimal pair, and plus cupping, if every nonzero c.e. degree __x__ below __a__ is cuppable. Let **NB** and **PC** be the sets of all nonbounding and plus cupping c.e. degrees, respectively. Both **NB** and **

We show that every graph G on n vertices with minimal degree at least n / k contains a cycle of length at least [ n / ( k -111. This verifies a conjecture of Katchalski. When k = 2 our result reduces t o the classical theorem of Dirac that asserts that if all degrees are at least i n then G is Hamil
