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. trusted wholesale clothing sites
