2-7. Solve the cargo-loading problem of Example 12.3-1 for each of the following sets of data: *(a) w1=4,r1=70,w2=1,r2=20,w3=2,r3=40,W=6 (b) w1=1,r1=15,w2=2,r2=30,w3=3,r3=40,W=4 A 4-ton vessel can be loaded with one or more of three items. The following table gives the unit weight, wi, in tons and the unit revenue in thousands of dollars, ri, for item i. The goal is to determine the number of units of each item that will maximize the total return. Because the unit weight wi and the maximum weight W are integers, the state xi assumes integer values only. A 4-ton vessel can be loaded with one or more of three items.
