GATE | GATE 2017 MOCK II | Question 26
Consider the following instance of knapsack problem:
The maximum weight of 12 is allowed in the knapsack.
Decreasing order of P i /W i is
X1, X4, X3, X5, X2
X1 –> profit = 15 and weight = 2
Including X4 –> profit = 15 + 16 and weight = 2 + 4 = 6
Including X3 –> profit = 40 and weight = 9
Now weight left = 3
Weight of X5 = 6 –> half of X5 can be included.
Profit = 40 + 17/2 = 48.5.
