Dynamic Programming: 8. A 4-ton vessel can be loaded with three items. The following data gives the unit weight, wi, in tons and the unit revenue in thousands of dollars, ri, for item i: w1 = 2, w2 = 3, w3 = 1, r1 = $31, r2 = $47, r3 = $14. Determine, the optimal solution by solving the problem as an integer knapsack problem using the dynamic programming approach.
