Computational experience with a group theoretic integer programming algorithm

TLDR
The innovative subroutines are shown to be efficient to compute and effective in finding good integer programming solutions and providing strong lower bounds for the branch and bound search.
Abstract
This paper gives specific computational details and experience with a group theoretic integer programming algorithm. Included among the subroutines are a matrix reduction scheme for obtaining group representations, network algorithms for solving group optimization problems, and a branch and bound search for finding optimal integer programming solutions. The innovative subroutines are shown to be efficient to compute and effective in finding good integer programming solutions and providing strong lower bounds for the branch and bound search.

An Appraisal of Some Shortest-Path Algorithms

TL;DR: In this article, five discrete shortest-path problems are treated: finding the shortest path between two specified nodes of a network, determining the shortest paths between all pairs of nodes in a network; determining the second, third, etc., shortest path; 4 determining the fastest path through a network with travel times depending on the departure time; and 5 finding the short path between specified endpoints that passes through specified intermediate nodes.
