Revisiting sparse dynamic programming for the 0/1 Knapsack Problem
The 0/1-Knapsack Problem is a classic NP-hard problem. There are two common approaches to obtain the exact solution: branch-and-bound (BB) and dynamic programming (DP). A socalled, "sparse" DP algorithm (SKPDP) that performs fewer operations than the standard algorithm (KPDP) is well known. To the best of our knowledge, there has been no quantitative analysis of the benefits of sparsity. We provide a careful empirical evaluation of SKPDP and observe that for a "large enough" capacity, C, the number of operations performed by SKPDP is invariant with respect to C for many problem instances. This ...
