Approximability of the Multiple Stack TSP
نویسنده
چکیده
STSP seeks a pair of pickup and delivery tours in two distinct networks, where the two tours are related by LIFO contraints. We address here the problem approximability. We notably establish that asymmetric MaxSTSP and MinSTSP12 are APX, and propose a heuristic that yields to a 1/2, 3/4 and 3/2 standard approximation for respectively Max2STSP, Max2STSP12 and Min2STSP12.

(Non)-Approximability for the Multi-criteria TSP(1, 2)
The approximability of multi-criteria combinatorial problems motivated a lot of articles. However, the non-approximability of this problems has never been investigated up to our knowledge. We propose a way to get some results of this kind which works for several problems and we put it into practice on a multi-criteria version of the traveling salesman problem with distances one and two (TSP (1,...
متن کاملApproximation Algorithms for Combinatorial Multicriteria Optimization Problems
The computational complexity of combinatorial multiple objective programming problems is investigated. INP-completeness and #P-completeness results are presented. Using two deenitions of approximability, general results are presented, which outline limits for approximation algorithms. The performance of the well known tree and Christoodes' heuristics for the TSP is investigated in the multicrit...
متن کاملApproximation Taxonomy of Metric TSP
The list below presents the best up to now known upper and lower approximation bounds for the instances of metric TSP (we refer also to another source on approximation algorithms for metric TSP [8]). It is intended to codify (at one glance) the (many) recent developments and improvements on the approximability of that problem. It is hoped to be useful in further research on the possible improve...
متن کاملA better differential approximation ratio for symmetric TSP
In this paper, we study the approximability properties of symmetric TSP under an approximation measure called the differential ratio. More precisely, we improve up to 3/4 − ε (for any ε > 0) the best differential ratio of 2/3 known so far, given in Hassin and Khuller, “z-Approximations”, J. of Algorithms, 41(2), 429-442, 2001.
متن کاملPolyhedral results and a branch-and-cut algorithm for the double traveling Salesman problem with multiple stacks
In the double TSP with multiple stacks, one performs a Hamiltonian circuit to pick up n items, storing them in a vehicle with s stacks of finite capacity q satisfying lastin-first-out constraints, and then delivers every item by performing a Hamiltonian circuit. We introduce an integer linear programming formulation with arc and precedence variables. We show that the underlying polytope shares ...
