Abstract: Abstract The paper presents reformulation techniques to reduce the complexity of a knapsack linear integer problem. Reformulation significantly reduces the number of standard branch and bound sub-problems required to verify optimality. Computational results of the various technique are given to compare the number of branch and bound iterations on some selected knapsack linear integer problems before and after the reformulation.
