Instances for the two-dimensional heterogeneous vector bin packing problem

The dataset consist of 56 instances for the two-dimensional heterogeneous vector bin packing problem. Six small instances with 10, 11, 12, 13, 15 and 20 items, as well as 50 randomly generated large instances were considered. Weights and volumes of items were randomly uniformly chosen integer values from [1;15] tons and [1;25]m3, respectively. The set of large instances had 5 instances with each of the following numbers of items: 50, 70, 100, 120, 150, 200, 350, 500, 750 and 1000. File structure: - number of items - weights of items - volumes of items
