Question

From the following code, explain how it works and calculate the time complexity

def bound_knapsack(i, current_weight, current_value, bound):

if i == n:

return current_value

if current_weight + weights[i] <= capacity:

# Include item i

with_i = bound_knapsack(i + 1, current_weight + weights[i], current_value + values[i], bound)

else:

with_i = float("-inf") # Cannot include item i

# Exclude item i

without_i = bound_knapsack(i + 1, current_weight, current_value, bound)

# Update bound (relaxatiole n)

bound = max(bound, with_i, without_i)

return bound

# Example usage:

n = 4

weights = [10, 20, 30, 40]

values = [60, 100, 120, 240]

capacity = 50

print("Branch and Bound:", bound_knapsack(0, 0, 0, float("-inf")))
