✦ Synopsis
We give linear-time algorithms for a class of parametric search problems on weighted graphs of bounded tree-width. We also discuss the implications of our results to approximate parametric search on planar graphs.

It is shown that for any positive integers k and w there exists a constant N ¼ N ðk; wÞ such that every 7-connected graph of tree-width less than w and of order at least N contains K 3;k as a minor. Similar result is proved for K a;k minors where a is an arbitrary fixed integer and the required conn
Let T be a b-ary tree of height n, which has independent, non-negative, n identically distributed random variables associated with each of its edges, a model previously considered by Karp, Pearl, McDiarmid, and Provan. The value of a node is the sum of all the edge values on its path to the root. Co
[•] is a lower integer form and α depends on k. We show that every k-edge-connected graph with k ≥ 2, has a d k -tree, and α = 1 for k = 2, α = 2 for k ≥ 3.
In this paper we find some exact values of \(n\)-widths in the integral metric with the Chebyshev weight function for the classes of functions that are bounded and analytic or harmonic in the interior of the ellipse with foci \(\pm 1\) and sum of semiaxes \(c\). We also construct optimal quadrature
