The generalized traveling salesman problem (GTSP) is an extension of the classical
traveling salesman problem (TSP) and it is among the most researched combinatorial …

This work addresses a soft-clustered vehicle routing problem that extends the classical
capacitated vehicle routing problem with one additional constraint, that is, customers are …

This paper investigates the clustered shortest-path tree (CluSPT) problem, a generalized
network design problem that has several applications in various areas such as network …

Abstract Medical Solid Wastes (MSWs) are major hazardous materials containing harmful
biological or chemical compounds that present public and environmental health risks. The …

This work studies a soft-clustered capacitated arc routing problem that extends the classical
capacitated arc routing problem with an important constraint. The problem has a set of …

The rapid development of modern cold chain logistics technology has greatly expanded the
sales market of agricultural products in rural areas. However, due to the uncertainty of …

A soft-clustered vehicle routing problem (SoftClu-VRP) is an important variant of the well-
known capacitated vehicle routing problem, where customers are partitioned into clusters …

In this paper, we make a comprehensive comparison in terms of the quality of the achieved
solutions, the corresponding execution time and impact of the genetic operators on the …

This paper deals with a multi-depot mixed vehicle routing problem under uncertain travel
times (MDMVRP-UT), where there are several different depots and a number of identical …

The clustered minimum routing tree problem (CluMRTP) extends the classical minimum
routing tree problem by considering a graph with vertices divided into a given number of …
