Traveling Salesman Problem [PDF]

open access: yes, 2015
Práce se zaměřuje na úpravu známých postupů ACO a GA s ohledem na zvyšování efektivity nalézaných řešení. Jsou zde prezentovány dva nové přístupy pro řešení TSP. Pomocí jednoho z nich lze také vytvořit počáteční populaci pro GA. Je uveden konkrétní návrh

A matheuristic for the traveling salesman problem with positional consistency constraints

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract We propose a matheuristic for the traveling salesman problem with positional consistency constraints, where we seek to generate a set of routes with minimum total cost, in which the nodes visited in more than one route (consistent nodes) must occupy the same relative position in all routes.

An Efficient Hybrid Ant Colony System for the Generalized Traveling Salesman Problem [PDF]

open access: yes, 2012
The Generalized Traveling Salesman Problem (GTSP) is an extension of the well-known Traveling Salesman Problem (TSP), where the node set is partitioned into clusters, and the objective is to find the shortest cycle visiting each cluster exactly once.

Quantum annealing of the Traveling Salesman Problem

open access: yes, 2004
We propose a path-integral Monte Carlo quantum annealing scheme for the symmetric Traveling Salesman Problem, based on a highly constrained Ising-like representation, and we compare its performance against standard thermal Simulated Annealing.

A formulation and a metaheuristic approach for the clustered vehicle routing problem with d‐relaxed priority rule

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract This paper investigates an extension of the vehicle routing problem in which, in addition to minimizing the distance traveled, the sequencing of customer visits is subject to precedence constraints that impose visiting priorities among customers.

Optimizing Movement Sequences for Step-and-Scan Lithography Equipment

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2013
The purpose of this work is to improve the throughput of step-and-scan lithography equipment to shorten the production time of a wafer. For this purpose, we propose a method for solving the MSOP (Movement Sequence Optimization Problem), which is the ...

Short Combinatorial Proof that the DFJ Polytope is contained in the MTZ Polytope for the Asymmetric Traveling Salesman Problem

open access: yes, 2017
For the Asymmetric Traveling Salesman Problem (ATSP), it is known that the Dantzig-Fulkerson-Johnson (DFJ) polytope is contained in the Miller-Tucker-Zemlin (MTZ) polytope. The analytic proofs of this fact are quite long.

Evaluation of drone system for thinning operations–a case study in Sweden

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Thinning operations in forestry typically involve a two‐machine system (TMS) with a harvester and a forwarder. Its productivity in different forest conditions is well documented. To date, drones have been used for data collection and surveillance but not as an alternative to a TMS.

Quantum heuristic algorithm for traveling salesman problem

open access: yes, 2012
We propose a quantum heuristic algorithm to solve a traveling salesman problem by generalizing Grover search. Sufficient conditions are derived to greatly enhance the probability of finding the tours with extremal costs, reaching almost to unity and they
