Scalable Computation of Topological Abstractions for Scalar Data
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Can the Agent with Limited Information Solve Travelling Salesman Problem?
Here, we develop new heuristic algorithm for solving TSP (Travelling Salesman Problem). In our proposed algorithm, the agent cannot estimate tour lengths but detect only a few neighbor sites. Under the circumstances, the agent occasionally ignores the NN

The selective travelling salesman problem
This paper deals with exact solutions for the Selective Traveling Salesman Problem - a TSP with profit at the nodes - by branch-and bound. The contribution is in the form of a new upper bound calculation as well as two node partitioning rules.

A matheuristic for the traveling salesman problem with positional consistency constraints
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.

Three-dimensional Euclidian Distance to Neutrosophic Number for Travelling Salesman Problem [PDF]
The main idea in this paper is to study the application of the novel greedy Dhouib Matrix-TSP1 (DM-TSP1) method to solve the Travel Salesman Problem with simple neutrosophic numbers. Here, the Euclidian distance is used to convert the neutrosophic number

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

The Symmetric Traveling Salesman Problem
Let M be an nXn symetric matrix, n, even, T, an upper bound for T_OPT, an optimal tour, sigma_T, the smaller-valued perfect matching obtained from alternate edges of T expressed as a product of 2-cycles. Applying the modified Floyd-Warshall algorithm to (sigma_T)^-1M^-, we construct acceptable and 2-circuit cycles some sets of which may yield circuits ...

Abstract We address the scheduling conflicting jobs on parallel identical machines problem with makespan minimization, a classical and computationally challenging variant of parallel machine scheduling. We develop and evaluate three distinct solution methodologies: a novel constraint programming (CP) formulation, and two metaheuristics: a multi ...
