Knapsack Problem: Algorithm Data Structures: Weight array: W[n]  To store weight values Profit array: P[n]  To store profit values Capacity  Given and will decrease after each step X[n]  To store 0, 1 or fraction depending upon object placement Weight = 0 (initially) and will increase towards capacity Profit = 0 and will be calculated by X[i] and P[i] Process: To select the object with best Pi/Wi Ratio. (Sorting)
