چکیده
The All-Colors Shortest Path (ACSP) is a recently introduced NP-Hard optimization problem, in which color assigned to each vertex of an edge weighted graph, and the aim find shortest path spanning all colors. solution can be not simple, that it possible visit multiple times same vertices if convenient choice. starting constrained or (ACSP-UE). We propose reduction heuristic based on transformation any ACSP-UE instance into Equality Generalized Traveling Salesman Problem one. Computational results show algorithm outperform best previously known

All Colors Shortest Path Problem
All Colors Shortest Path problem defined on an undirected graph aims at finding a shortest, possibly non-simple, path where every color occurs at least once, assuming that each vertex in the graph is associated with a color known in advance. To the best of our knowledge, this paper is the first to define and investigate this problem. Even though the problem is computationally similar to general...
متن کاملApproximation Solutions for Time-Varying Shortest Path Problem
Abstract. Time-varying network optimization problems have tradition-ally been solved by specialized algorithms. These algorithms have NP-complement time complexity. This paper considers the time-varying short-est path problem, in which can be optimally solved in O(T(m + n)) time,where T is a given integer. For this problem with arbitrary waiting times,we propose an approximation algorithm, whic...
متن کاملOn the Exponent of the All Pairs Shortest Path Problem
The upper bound on the exponent, ω, of matrix multiplication over a ring that was three in 1968 has decreased several times and since 1986 it has been 2.376. On the other hand, the exponent of the algorithms known for the all pairs shortest path problem has stayed at three all these years even for the very special case of directed graphs with uniform edge lengths. In this paper we give an algor...
متن کاملThe Lagrangian Relaxation Method for the Shortest Path Problem Considering Transportation Plans and Budgetary Constraint
In this paper, a constrained shortest path problem (CSP) in a network is investigated, in which some special plans for each link with corresponding pre-determined costs as well as reduction values in the link travel time are considered. The purpose is to find a path and selecting the best plans on its links, to improve the travel time as most as possible, while the costs of conducting plans do ...
متن کاملThe shortest path problem
The shortest path problem is solved and applied to the calculations of half lives with respect to spontaneous fission of heavy nuclei. The dynamical programming method of Bellman and Kalaba is used to find the fission path in the d-dimensional space of deformation parameters. Fission half lives of heavy isotopes (100<Z<110) are shown and compared to the experimental data. 1. Introductory remark...
