CSE231: Assignment Three 

A polynomial of a real valued variable  x  is an expression of the form a

n

x

n 

+ an-1

x

n-1 

+ … + 

a

1

x

1

+ a0

where a0

, …, a

n

are real constants, called coefficients. For instance, 2.5x

3

+1.2x-5 is 

a polynomial of  x  with a3

=2.5, a2

=0, a1

=1.2 and a0=-5. In this project, you are required to 

develop a class named Polynomial that supports symbolic manipulation of polynomials of a 

fixed variable x, that is, all polynomials are polynomials of the same variable  x. Your class 

must at least support operations for 

1.  Constructing a polynomial given an array of coefficients. For example, given the 

float point number array {2.5,0.0,1.2,-5}, the operation constructs a Polynomial 

object representing 2.5x

3

+1.2x-5. This is a constructor. 

2.  Adding  one  polynomial  to  another.  For  example,  if  this  object  represents 

2.5x

3

+1.2x-5 then adding another object representing 7x

4

+2x

3

+x

2

+3 to this  object 

changes this object so that it represents 7x

4

+5.5x

3

+x

2

+1.2x–2. Note that the ranks 

(the largest exponent) of the two polynomials are not necessary the same. 

3.  Multiplying  one  polynomial  by  another.  For  example,  if  this  object  represents 

2x

2

+x-5 then multiplying it by another object representing 3x

3

+x

2

+3 changes this

object  so  that  it  represents  6x

5

+5x

4

-14x

3

+x

2

+3x-15.  Again  the  ranks  of  the  two 

polynomials are not necessary the same.

4.  Evaluating  a  polynomial  for  a  given  value  for  x.   For  instance,  if  this  object 

represents 2x

2

+x-5 then evaluating it for x=2 yields 5. 

5.  Converting a Polynomial object to a string so that the Polynomial object can be 

displayed.  If  this  object  represents  3x

3

+x

2

-1  then  the  method  should  return 

“3*x^3 + x^2 – 1” although “3*x^3 + 1*x^2 + 0*x^1 + (-1)” is acceptable 

1.  Specify, design and implement Polynomial. Your implementation must use linked lists 

to represent polynomials. 

2.  Write an interactive test program that tests all the public methods of the Polynomial 

class.

Please submit the following. 

  Analysis: test data;

  Design: 

1.  Class diagrams showing representation of data;

2.  A class invariant for each class;

3.  Pre/Post conditions for required operations;

4.  Algorithms for required operations. Algorithms can be described in English, 

flow diagrams, or sequence diagrams;

  Code; 

  Screen snapshots of test runs. 

 

The essence of presentation is making yourself known, along with your ideas. There are at least two reasons to begin the planning of any presentation with a consideration of yourself. The first is that your knowledge of yourself and what you are thinking

 

Assignment: Provide a reflection of at least 500 words (or 2 pages double spaced) of how the knowledge, skills, or theories of operations security have been applied or could be applied, in a practical

Assignment: Provide a reflection of at least 500 words (or 2 pages double spaced) of how the knowledge, skills, or theories of operations security have been applied or could be applied, in a practical manner to SA admin(software administration).

Requirements:

Provide a 500 word (or 2 pages double spaced) minimum reflection.

Use of proper APA formatting and citations. If supporting evidence from outside resources is used those must be properly cited.

Share a personal connection that identifies specific knowledge and theories from this course.

Demonstrate a connection to your current work environment. If you are not employed, demonstrate a connection to your desired work environment. 

You should NOT, provide an overview of the assignments assigned in the course. The assignment asks that you reflect how the knowledge and skills obtained through meeting course objectives were applied or could be applied in the workplace. 

Provide your own short Java code example that uses a For or While loop. Be sure to test and describe what your code is doing.

Use Java comments to document your code.

*This must be completed to display Java comments above each line of code to explain what is happening. I must be provided with the Java code/comments so that I may compile, run, and test the program.*

Write a research paper in APA format on a subject of your choosing that is related to Business Intelligence.  Integrate what you have learned from the course resources (.e.g. Textbook Readings, Discussion Board Posts, Chapter Presentations) into your document.

As you consider the topic for your research paper, try and narrow the subject down to a manageable issue.  Search for academic journal articles (i.e. peer reviewed) and other sources related to your selected subject.  Because this is a research paper, you must be sure to use proper APA format citations.  

Your paper must include an introduction stating what you paper is about and a logical conclusion.

This paper must contain a minimum of 1500 words of content and use at least 5 peer reviewed sources.  Peer reviewed sources include:  Academic Journal Articles, Textbooks, and Government Documents.  At least one of the textbooks for this course must be used as a source for this paper.

Example Topics:

• Use of Artificial Intelligence in Decision Support Systems.
• Business Uses of Natural Language Processing.
• Use of Game Theory in Business Intelligence Systems.
• Use of Decision Trees in Automated Systems.
• The Social Networks for Collaborative Decision Making.
