A QUBO Model for the Traveling Salesman Problem with Time Windows

open access: yesAlgorithms, 2019
This work focuses on expressing the TSP with Time Windows (TSPTW for short) as a quadratic unconstrained binary optimization (QUBO) problem. The time windows impose time constraints that a feasible solution must satisfy. These take the form of inequality

The C. elegans TspanC8 tetraspanin TSP-14 exhibits isoform-specific localization and function.

open access: yesPLoS Genetics, 2022
Tetraspanin proteins are a unique family of highly conserved four-pass transmembrane proteins in metazoans. While much is known about their biochemical properties, the in vivo functions and distribution patterns of different tetraspanin proteins are less

Proposal of an Effective Computation Environment for the Traveling Salesman Problem Using Cloud Computing

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
Various methods have been proposed to solve the traveling salesman problem, referred to as the TSP. In order to solve the TSP, the cost metric (e.g., the travel time and distance) between nodes is needed.
