A new constructive heuristic driven by machine learning for the traveling salesman problem

Mele, Umberto Junior ; Gambardella, Luca Maria ; Montemanni, Roberto

In: Algorithms, 2021, vol. 14, no. 9, p. 25

Recent systems applying Machine Learning (ML) to solve the Traveling Salesman Problem (TSP) exhibit issues when they try to scale up to real case scenarios with several hundred vertices. The use of Candidate Lists (CLs) has been brought up to cope with the issues. A CL is defined as a subset of all the edges linked to a given vertex such that it contains mainly edges that are believed to be...

Filipponi, Chiara ; Schulz, Peter J. ; Petrocchi, Serena

In: Behavioral sciences, 2020, vol. 10, no. 12, p. 8 p

Evidence demonstrated that self-mastery and coping ability predict mental health in adults and children. However, there is a lack of research analyzing the relationships between those constructs in parents and children. Self-report data from 89 dyads (adolescents’ mean of age = 14.47, SD = 0.50; parents’ mean of age = 47.24, SD = 4.54) who participated in waves 17, 18, and 19 (following T1,...
