As the title suggest, I want do know if there is an algorithm that works with different size of bins and different size of weights. for example I have sorted list of items L1 [20,20,20,55,60,80...] and sorted list of bins size that I can use L2 [200,350,500]. I can use with how many bins I want. I have tried to read about cutting stock problem but there the planks are fixed and so in the bin packing algorithms. can someone put me in the right direction? ty.
