Automata and Computability

1. Suppose the languages recognized by DFAs M and N are L1 and L2 respectively. How can

we use DFAs M and N to construct a DFA that recognizes the language L1∩L2? [Can you

use De Morgan’s Law?]

2. Show by giving an example that, if M is an NFA that recognizes language L, swapping the

final and non-final states in M doesn’t necessarily yield a new NFA that recognizes the

complement of L. Is the class of languages recognized by NFAs closed under

complement? Explain your answer.

Improving Decision Making

For this project, use the following hypothetical situation:

You have found a new job in Denver, Colorado and would like to purchase a home in that area. Ideally, you would like to find a single-family house with at least three bedrooms and one bathroom that costs between $150,000 and $225,000 and finance it with a 30-year fixed rate mortgage. You can afford a down payment that is 20 percent of the value of the house. Before you purchase a house, you would like to find out what homes are available in your price range, find a mortgage, and determine the amount of your monthly payment. You would also like to see how much of your mortgage payment represents principal and how much represents interest. Use the Yahoo! real estate site (http://homes.yahoo.com/) to help you with the following tasks:

  1. Locate homes in your price range in Denver, Colorado. Find out as much information as you can about the houses, including the real estate listing agent, condition of the house, number of rooms, and the school district.
  2. Find a mortgage for 80 percent of the list price of the home.
  3. After selecting a mortgage, calculate your closing costs.
  4. Calculate the monthly payment for the mortgage you select.
  5. Calculate how much of your monthly mortgage payment represents principal and how much represents interest, assuming you do not plan to make any extra payments on the mortgage.

Next, complete these same steps using a different online source, such a Zillow.

When you are finished, evaluate the whole process for each website. Each evaluation should cover the following items:

  • Ease of use of the site and your ability to find information about houses and mortgages
  • Accuracy of the information you found
  • Breadth of choice of homes and mortgages
  • How helpful the whole process would be if you were actually in the situation described in this project

Now compare the Yahoo site with the other site you chose. For each of the areas you discussed in your evaluation, which website has the advantage and why? Be specific and provide examples.

Finally, what improvements or enhancements would you recommend for each site?

Compose a four-page (minimum) essay, not including a cover page, a reference page, or any charts or visual items. You should include a chart to illustrate and compare the data you found from the two separate sites. You must use APA format and cite at least two outside sources.

The following is the general structure of the Research Report 

Chapter 1- Background/Introduction (3 – 4 pages) 

In this section, present enough information about the proposed work so that the reader understands the general context or setting. It is also helpful to include a summary of how this document is organized. 

Introduction 

This section introduces the reader to the structural content of your Research Report 

Problem Statement and Purpose of Research 

In this section, present a concise statement of a research-worthy problem to be addressed (i.e., why the work should be undertaken – don’t state “it was a requirement of the professor”). Follow the statement of the problem with a well-supported discussion of its scope and nature. The discussion of the problem should include: what the problem is, why it is a problem, how the problem evolved or developed, and the issues and events leading to the problem. Your problem statement must be clear, concise, to the point and able to be articulated in no more than three sentences. 

Relevance and Significance 

This section provides the necessary support for both the problem statement of your study. Consider the following questions and support your discussion by citing the research literature: 

  •   Why is there a problem? What groups or individuals are affected?
     
  •   How far-ranging is the problem and how great is its impact? What’s the benefit of solving the problem?
     
  •   What has been tried without success to correct the situation? Why weren’t those attempts successful?
     
  •   What are the consequences of not solving the problem?
     
  •   How does the goal of your study address the research problem and how will your proposed study offer
    promise as a resolution to the problem?
     
  •   How will your research add to the knowledge base?
     

 

Font Style: Times New Roman throughout the document 

 

Font color: Black (including headings)

  •   What is the potential for generalization of your results?
     
  •   What is the potential for original work?
    Research Questions
    In this section you will define the research questions you expect to answer in your finding / results / conclusion sections. The research question(s) must be directly related to the problem statement and introduce the reader to their respective relationships. The answers to the research question(s) need to be either qualitative or quantitative.
    Barriers and Issues
    In this section, identify how the problem is inherently difficult to solve. You should also show how the solution you propose are difficult to obtain (unlike a book report). You should show the study you propose is of adequate difficulty to warrant a successful grade assignment.
    Chapter 2 – Review of the Literature (6-8 pages)
    In this section, it is important to clearly identify the major areas on which you will need to focus your research in order to build a solid foundation for your study in the existing body of knowledge. The literature review is the presentation of quality literature in a particular field that serves as the foundation and justification for the research problem, research questions or hypothesis, and methodology. You will develop a more comprehensive review of the literature as part of your report.
    Chapter 3 – Approach/Methodology (1 – 2 pages)
    Describe how you plan to address your research problem and accomplish your stated goal. List the major steps that must be taken to accomplish the goal and include a preliminary discussion of the methodology and specific research methods you plan to implement. Although specific details are not required at this point, you must provide adequate discussion of the general process you will follow to implement your research methodology.
    Chapter 4: Findings, Analysis, and Summary of Results (2 – 4 pages)
    Chapter 4 includes an objective description and analysis of the findings, results or outcomes of the research. Limit the use of charts, tables, figures to those that are needed to support the narrative. Most of these illustrations can be included as part of the Appendixes.
    The following topics are intended to serve as a guide:
     
  •   Data analysis
     
  •   Findings & discussion
     
  •   Analysis
     
  •   Summary of results & discussion Chapter 5: Conclusions (2 – 4 pages)
     

 Conclusions – Clearly state the conclusions of the study based on the analysis performed and results achieved. Indicate by the evidence or logical development the extent to which the specified objectives have been

accomplished. If the research has been guided by hypotheses, make a statement as to whether the data supported or rejected these hypotheses. Discuss alternative explanations for the findings, if appropriate. Delineate strengths, weaknesses, and limitations of the study. 

  •   Implications – Discuss the impact of the work on the field of study and its contributions to knowledge and professional practice. Discuss implications for future research.
     
  •   Recommendations – Present recommendations for future research or for changes in research methods or theoretical concepts. As appropriate, present recommendations for changes in academic practice, professional practice, or organizational procedures, practices, and behavior.
    References
