Chapter 12, Problem 12RQ
Explanation of Solution
Make-versus-buy decision:
- The decision regarding whether to obtain the necessary software from internal or external sources, simply because it costs too much and takes too long to build a quality
information system . - It is the act of deciding between manufacturing a product in-house or buying it from an external supplier.
- Quantitative analysis, such as associated cost of production and whether the business can produce at the desired levels.
Justification:
- The analysis team assesses the software marketplace to determine whether existing packages can meet the organization’s needs using a tool called request for proposal (RPF)
- RFP is a formal document that outlines an organization’s software or hardware needs and requests vendors to develop a detailed proposal of how they would meet those needs and at what cost.
- The RFP outlines the desired system and its requirements and It identifies the pieces of data that the software vendor must include in the proposal...

- You are given a rope of length n meters and scissors that can cut the rope into any two pieces. For simplification, only consider cutting the rope at an integer position by the meter metric. Each cut has a cost associated with it, c(m), which is the cost of cutting the rope at position m. (You can call c(m) at any time to return the cost value.) The goal is to cut the rope into k smaller pieces, minimizing the total cost of cutting. B Provide the pseudo-code of your dynamic programming algorithm f(n,k) that will return the minimum cost of cutting the rope of length n into k pieces. Briefly explain your algorithm. What is the benefit of using dynamic programming for this problem? What are the key principles of dynamic programming used in your algorithm?arrow_forwardDetermine whether each of the problems below is NP-Complete or P A. 3-SAT B. Traveling Salesman Problem C.

Based on our lecture on NP-Complete, can an NP-Complete problem not have a polynomial-time algorithm? Explain your answer. 2. Prove the conjecture that if any problem in NP is not polynomial-time solvable, then no NP-Complete problem is polynomial-time solvable. (You can't use Theorem 1 and 2 directly) 3. After you complete your proof in b), discuss how this conjecture can be used to solve the problem of whether P=NP.arrow_forward
