An efficient algorithm for determining the length of the longest dead path in a "LIFO" branchandbound exploration schema by
Stefano Pallottino(
Book
)
5 editions published between 1979 and 1980 in English and held by 11 WorldCat member libraries worldwide
The length of the longest dead path (LLDP) is a widely used parameter in estimating the efficiency of branchandbound optimization algorithms that employ the LIFO exploration schema. Thanks to two original theorems, we are able to present a particularly attractive procedure for determining of the LLDP. In fact this procedure requires a number of storage variables which is independent of problem size and very small; moreover, the procedure is selfcontained in the sense that it can be externally attached to any LIFO branchandbound program without interfering with its algorithms and data structures.

Polynomial auction algorithms for shortest paths by
Dimitri P Bertsekas(
Book
)
5 editions published in 1992 in English and held by 6 WorldCat member libraries worldwide
Abstract: "In this paper we consider strongly polynomial variations of the auction algorithm for the single origin/all destinations shortest path problem. These variations are based on the idea of graph reduction, that is, deleting unnecessary arcs of the graph by using certain bounds naturally obtained in the course of the algorithm. We study the structure of the reduced graph and we exploit this structure to obtain algorithms with O(n.min[m, n log n]) and O(n²) running time. Our initial computational experiments are encouraging, showing that these algorithms outperform their closest competitors on randomly generated dense problems."

Implicit enumeration of hyperpaths in logit models for transit networks by
Sang Nguyen(
Book
)
2 editions published in 1992 in English and held by 4 WorldCat member libraries worldwide
Abstract: "This paper investigates the application of multinomial logit distribution models to urban transit networks where every set of competitive transit lines is describes [sic] by a particular graph structure called a hyperpath. It shows that the standard multinomial logit model does not lead to a practical algorithmic implementation similar to that obtained for the private vehicle networks and should be replaced with a hierarchical logit. This latter model seems to transcend the inherent limitations of the simple logit model which are amplified by the hyperpath framework."

Hypergraph models and algorithms for the assembly problem by Giorgio Gallo(
Book
)
2 editions published in 1992 in English and held by 2 WorldCat member libraries worldwide
Abstract: "We consider the problem of finding an optimal set of feasible assembly operations in order to derive a desired product from a given set of parts. We show that optimal solutions, under different objective functions, can be obtained by means of computationally efficient hypergraph algorithms. In particular, we consider the case in which one wants to minimize the duration with an unlimited degree of parallelism. Finally, a new fast algorithm is presented in order to assign operations to robots in an optimal way when the degree of parallelism is bounded."
