Give a nondeterministic polynomial time algorithm for the SUM OF SUBSETS problem. Define the transformation from the PARTITION problem to the SUM OF SUBSETS problem.

/in /by
  1. Let X(1..n) and Y(1..n) contain two lists of n integers, each sorted in nondecreasing order. Give the best (worst-case complexity) algorithm that you can think for finding

(a) the largest integer of all 2n combined elements.

(b) the second largest integer of all 2n combined elements.

(c) the median (or the nth smallest integer) of all 2n combined elements.

For instance, X = (4, 7, 8, 9, 12) and Y = (1, 2, 5, 9, 10), then median = 7, the nth smallest, in the combined list (1, 2, 4, 5, 7, 8, 9, 9, 10, 12). [Hint: use the concept similar to binary search] 1-to-2 PARTITION:

Instance: A finite set of positive integers Z = { z1 , z2 , … , zn }.

Question: Is there a subset Z’ of Z such that Sum of all numbers in Z’ = 2 x Sum of all numbers in Z-Z’

(a) Obtain the dynamic programming functional equation to solve the 1-to-2 PARTITION problem.

(b) Give an algorithm to implement your functional equation.

(c) Give an example of 5 numbers with a total of 21 as an input instance for 1-to-2 PARTITION problem, and show how your algorithm works on this input instance.

(d) What is the complexity of your algorithm?

  1. Decide True or False for each of the followings. You MUST briefly justify your answer.

Satisfiability:

Instance: Set U of variables, collection C of clauses over U.

Question: Is there a satisfying truth assignment for C?

(a) If P NP, then no problem in NP can be solved in polynomial time deterministically.

(b) If a decision problem A is NP-complete, proving that A is reducible to B, in polynomial time, is sufficient to show that B is NP-complete.

(c) It is known that SAT (Satisfiability) is NP-complete, and 3SAT (all clauses have size

3) is NP-complete. 1SAT (all clauses have size 1) is also NP-complete.2

  1. Given that PARTITION problem (described below) is a NP-Complete problem, prove that the SUM OF SUBSETS problem (described below) is NP-Complete by reducing

PARTITION problem to it.

PARTITION:

Instance: A finite set of positive integers Z = { z1 , z2 , … , zn }.

Question: Is there a subset Z’ of Z such that Sum of all numbers in Z’ = Sum of all numbers in Z-Z’

SUM OF SUBSETS:

Instance: A finite set of positive integers A = { a1, a2, … , am } and M.

Question: Is there a subset A’ in A s.t. ai = M? ai in A’

(a) Give a nondeterministic polynomial time algorithm for the SUM OF SUBSETS problem.

(b) Define the transformation from the PARTITION problem to the SUM OF SUBSETS problem.

(c) Explain that the transformation described in part (b) satisfies: if the partition problem has a solution then the sum-of-subsets has a solution, and vice versa.

  1. Prove that the 0/1 KNAPSACK problem is NP-Hard. (One way to prove this is to prove the decision version of 0/1 KNAPSACK problem is NP-Complete. In this problem, we use PARTITION problem as the source problem.)

(a) Give the decision version of the O/1 KNAPSACK problem, and name it as DK.

(b) Show that DK is NP-complete (by reducing PARTITION problem to DK).

(c) Explain why showing DK, the decision version of the O/1 KNAPSACK problem, is NP-Complete is good enough to show that the O/1 KNAPSACK problem is NP -hard.

  1. Optimization PS(3) Problem: Given a set of n program and three storage devices.

Let si be the amount of storage needed to store the ith program. Let L be the storage capacity of each disk. Determine the maximum number of these n programs that can be stores on the three disks (without splitting a program over the disks).

Use the Approximation PS Algorithm given in the class for the PS(3) problem given above. Show that the following is true.

Let the approximation PS algorithm returns a number C, and let C* be the optimal (maximum) number of programs that can be stores on the three disks.

(a) Show that the above approximation PS algorithm gives the performance ratio of C* (C + 2) OR C* / C 1 + 2/C.

(b) Give an example that achieves the performance ratio of C* =

Warranty

Look at a warranty for an iPod, a cell phone, or computer. Consider the following questions:

  • Identify the parties to the warranty.
  • Is it covered by the UCC?
  • What are the implied warranties? What are the express warranties?
  • What services does the company provide and under what circumstances.
  • Do you think the consumer is properly protected? Why or why not?

REMEMBER a limited warranty IS NOT the same as a implied warranty!!!!!

What activities would you recommend early in the system development effort to mitigate such technical and/or programmatic risks? For each mitigation activity, explain whether the activity will lower the likelihood of the risk, or the consequences of the risk, or both.

/in /by

Assignment

Part A

You have been promoted to the role of Systems Engineer by your company and are directed to work on a major new system development effort that involves new technology*. Obviously, this represents a major technical (if not programmatic) risk area for your employer. What activities would you recommend early in the system development effort to mitigate such technical and/or programmatic risks**? For each mitigation activity, explain whether the activity will lower the likelihood of the risk, or the consequences of the risk, or both. [70]

 

Part B

While the techniques you discussed in Part A focused on mitigating system risks, other Systems Engineering (SE) concepts and techniques can be employed to enhance system safety. One of those concepts is the architecture of the system.

The SE Management team overseeing this project has also asked you to explain how the concept of system architecture can be used to enhance the overall safety of systems like the one you considered in Part A*. [30]

 

Assessment Criteria for Part A

The student’s answer for Part A should clearly demonstrate that the following concepts have been understood in relation to the specified problem and (where required) applied in a logical manner:

A1) Risks which can arise during the development of the type of system being described and how those risks are evaluated in terms of their likelihood and consequences, [15]

A2) How technology readiness is assessed and the impact of technology maturity on the success of the type of system being described, [15]

A3) The mitigation activities that should be performed in order to address the identified risks in the type of system being described, at what stage(s) in the development of that system they should be performed, and the extent to which those activities will lower the likelihood and/or the consequences of the identified risks. [40]

 

Assessment Criteria for Part B

The student’s answer for Part B should clearly demonstrate that the following concepts have been understood in relation to the specified problem and (where required) applied in a logical manner:

B1) The architecture of the system being described should be chosen according to the intended purpose of that system, [10]

B2) How the architecture of the system being described affects its non-functional requirements (specifically, the safety of that system). [20]
