Abstract

We discuss relationships between the solution to an integer-programming problem and the solution to its relaxed linear-program-ming problem in terms of the distance that separates them and related bounds. Assuming knowledge of a subset of extreme points, we develop bounds for associated convex combinations and show how improved bounds on the integer-programming problem's objective function and variables can be obtained.
