• the problem to address is a knapsack problem which reads as follows: Given a set of items, each with a weight and a value, determine the number of each item to include in a collection so that the total weight is less than or equal to a given limit, and the total value is as large as possible.

Compare stepwise refinement to top-down and bottom-up architecture methodology.

• Discuss how stepwise refinement links to structured design.
• Apply stepwise refinement on the selected problem.
• Rationalize on why you need to delay any language-specific activity as much as possible.
