Bin packing with divisible item sizes
WebThe bin packing problem with divisible item sizes and rejection penalties (the BP– DR problem, for short) is defined as follows. Given a lot of bins with same capacity … Webpacking with other restricted form of item sizes includes divisible item sizes [7] (where each possible item size can be divided by the next smaller item size) and discrete item …
