all different container capacities seem to be much more difficult
than the problem with all the same container capacity.
Thus, here, we deal with both types of problems.
As Raidl [4] mentioned, MCPP comprises similarities to
the knapsack problem and the bin packing problem. But,
MCPP has much more difficulty in the context that it must
solve two dependent parts simultaneously: (a) select items
for packing, and (b) distribute chosen items over available
containers. Thus, MCPP also belongs to the family of NPhard
problems, meaning that it is ever unlikely that we ever
can devise polynomial algorithms to solve it exactly.
Therefore, to use an exact algorithm like a branch and
bound method for solving this problem may require much
computation time. Nevertheless, the branch and bound
methods, which were devised by Martello and Toth [2]
and Pisinger [3], had shown very good performance. Especially,
the MULKNAP algorithm derived by Pisinger out
