The whole benchmark is composed by 66 instances comprised by 5 to 30 customers and 3 to 9 recharge stations. All instances are solved to proven optimality. Instances and optimal solutions are presented in xml format, compliant with the VRP-rep specifications. The <a href="https://vrp-rep.github.io/mapper/">VRP-rep instance mapper</a> was used to draw the graph of each instance (and its solution) in png format.<h2>Dataset A</h2> This dataset was derived from the Solomon dataset, by relaxing the time windows constraints: instances have up to 15 customers (the last part of the name indicates the size of each instance) and 5 stations, with a single technology. Some of these instances are very small and not challenging; they serve mainly to make a comparison between the results of similar problems. Instances in dataset A are splitted in three classes: C (clustered), R (random) and RC (random-clustered), according to distances between customers. This dataset contains 12 instances for each class. <h2>Dataset B</h2> Instances in this dataset have 10 customers, up to 5 vehicles, up to 9 stations and 3 technologies. This dataset contains 20 instances. <h2>Dataset C</h2> This dataset was adapted from the Solomon dataset: all instances have 30 customers, 7 vehicles, 5 stations and 3 technologies. In this dataset customer locations are clustered. This dataset contains 10 instances.CC0
