A Theoretical Approach for Structuring and Analysing Knowledge Provenance for Visual Analytics
Computer Graphics Forum, EarlyView.VAKG unfolds the interactions within the current knowledge model (A) into a temporal knowledge graph (B), which is structured as a 4‐way graph containing two temporal (green) and two static (yellow) knowledge graphs. By using VAKG, one can structure and store the user's knowledge‐gathering process and all related interactions for eventual analysis (C).

Optimization of Multiple Traveling Salesman Problem Based on Simulated Annealing Genetic Algorithm
MATEC Web of Conferences, 2017 It is very effective to solve the multi variable optimization problem by using hierarchical genetic algorithm. This thesis analyzes both advantages and disadvantages of hierarchical genetic algorithm and puts forward an improved simulated annealing ...

Data Collection Task Planning of a Fixed-Wing Unmanned Aerial Vehicle in Forest Fire Monitoring
IEEE Access, 2021 This article studies the data collection task planning for a fixed-wing unmanned aerial vehicle (UAV) in forest fire monitoring. Multiple wireless-based detection nodes (DNs) are distributed in high-risk areas of the forest to monitor the surrounding ...

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

International 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.

Maximum Scatter TSP in Doubling Metrics
, 2016 We study the problem of finding a tour of $n$ points in which every edge is long. More precisely, we wish to find a tour that visits every point exactly once, maximizing the length of the shortest edge in the tour. The problem is known as Maximum Scatter

An Optimal Control Theory for the Traveling Salesman Problem and Its Variants [PDF]
, 2020 We show that the traveling salesman problem (TSP) and its many variants may be modeled as functional optimization problems over a graph. In this formulation, all vertices and arcs of the graph are functionals; i.e., a mapping from a space of measurable ...

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