The main goal of Vehicular Ad-Hoc NETworks (VANETs) is to improve safety, efficiency and comfort in everyday road travel. The communication quality in these networks is highly degraded when the number of vehicles is very large in a small geographic area or when vehicles do not cooperate in packet forwarding. Groups are here proposed to avoid these problems by decreasing the number of packets sent...
In the field of single-objective optimization, hybrid variants of gradient-based methods and evolutionary algorithms have been shown to perform better than an evolutionary method by itself. This same idea has been recently used in Evolutionary Multiobjective Optimization (EMO), obtaining also very promising results. In most cases, gradient information is used along the whole process, which involves...
