WebHowever, this chapter will cover 0-1 Knapsack problem and its analysis. In 0-1 Knapsack, items cannot be broken which means the thief should take the item as a whole or should leave it. This is reason behind calling it as 0-1 Knapsack. Hence, in case of 0-1 Knapsack, the value of xi can be either 0 or 1, where other constraints remain the same. WebGreedy knapsack algorithm Algorithm chooses element with highest value/weight ratio first, the next highest second, and so on until it reaches the capacity of the knapsack.
