WebBin packing with other restricted form of item sizes in-cludes divisible item sizes [8] (where each possible item size can be divided by the next smaller item size) and discrete item sizes [6] (where possible item sizes are {1/k,2/k,··· ,j/k} for some 1 ≤ j ≤ k). For d-D packing, items of restricted WebBin packing. Divisible item sizes. Analysis of algorithms. A key problem in the management of data centers is how to provision virtual machines based on the available physical machines, because an optimized placement can lead to signiﬁcant reduction in energy consumption. This problem can be formulated as bin
