In this paper, a novel methodology is proposed to solve a cooperative multi-depot vehicle routing problem. We establish a mathematical model for multi-owner VRP in which each owner (i.e. player) manages single or multiple depots. The basic idea consists of offering an option that owners cooperatively manage the VRP to save their costs. We present cooperative game theory techniques for cost savi...

in the present study, the cooperative and diminutive interplay between halogen, hydride, and cation-σ interactions are studied in hmgh···li+(na+)···nccl, li+(na+)···hmgh···clcn and hmgh···clcn···li+(na+) complexes by means of ab initio calculations. to better understand the cooperative or diminutive effects in the ternary systems, the corresponding binary complexes are also considered. the esti...

A fundamental goal of evolutionary ecology is to understand how asymmetric competition influences phenotype expression, yet few studies have quantified the relative effects of intraand interspecific competition on phenotypes. We examined the effects of intraand interspecific larval competition on both discrete and continuous phenotype expression of the facultatively paedomorphic mole salamander...

In the present study, the cooperative and diminutive interplay between halogen, hydride, and cation-σ interactions are studied in HMgH···Li+(Na+)···NCCl, Li+(Na+)···HMgH···ClCN and HMgH···ClCN···Li+(Na+) complexes by means of ab initio calculations. To better understand the cooperative or diminutive effects in the ternar...

This paper proposes a methodology that uses hybrid systems to model multiple robots in the execution of cooperative tasks. Basically, each robot is represented by a hybrid automaton and the cooperative task execution is modeled by the composition of several automata. We describe in details our approach to perform the composition of these automata and demonstrate the effectiveness of the propose...

An overview of the iris image segmentation methodologies for biometric purposes is presented. The main focus is on the analysis of the ability of segmentation algorithms to process images with heterogeneous characteristics, simulating the dynamics of a non-cooperative environment. The accuracy of the four selected methodologies on the UBIRIS database is tested and, having concluded about their ...
