MAT 2051 Unit 5 Discussion DQ1 Data Mining, Time Complexity, and Algorithms
In Appendix C, you read about different programming control structures used to write pseudocode and actual computer algorithms, such as if statements, while and for loops, and function calls. For this discussion, assume you work for a data mining company and your job is to write a program to find information on various Web sites pertaining to sales of the Lenovo X200. After your algorithm finds this data, more complex analysis will be done to extract more meaningful information from the data.
Your algorithm is going to scan different sites and search for the character string “Lenovo X200.” Assume you decide to use an algorithm similar to Text Search (see algorithm 4.2.1 on page 178 of your text for an explanation of what this is). If the algorithm finds a site that contains the string (that is, Lenovo X200), assume that it then stores all data or all the text on that particular site into a storage area.
To understand this problem fully, answer the following questions:
What is data mining?
What is a character string?
What is the worst case run time of this algorithm in terms of p, m, t, n (that is, what is O)?
How long do you think it will take this algorithm to run? Note the time complexity as O (run time in terms of n).
Assume that each Web site, on average, has character strings of length 10,000 and that the length of the character string “Lenovo X200” is 11. How many computations will the algorithm need to make per site?
Why is speed and the analysis of algorithm speed so important?

Response Guidelines
Read your peers’ posts and respond to two. Did you arrive at the same time complexity calculation? Explain why or why not.

Follow specific instructions indicated in the assignment and use this checklist to help ensure correct grammar and APA formatting. Refer to the APA resources available in the GCU Library and Student Success Center.
☐ APA paper template (located in the Student Success Center/Writing Center) is utilized for the correct format of the paper. APA style is applied, and format is correct throughout.
☐ The title page is present. APA format is applied correctly. There are no errors.
☐ The introduction is present. APA format is applied correctly. There are no errors.
☐ Topic is well defined.
☐ Strong thesis statement is included in the introduction of the paper.
☐ The thesis statement is consistently threaded throughout the paper and included in the conclusion.
☐ Paragraph development: Each paragraph has an introductory statement, two or three sentences as the body of the paragraph, and a transition sentence to facilitate the flow of information. The sections of the main body are organized to reflect the main points of the author. APA format is applied correctly. There are no errors.
☐ All sources are cited. APA style and format are correctly applied and are free from error.
☐ Sources are completely and correctly documented on a References page, as appropriate to assignment and APA style, and format is free of error.
Scholarly Resources: Scholarly resources are written with a focus on a specific subject discipline and usually written by an expert in the same subject field. Scholarly resources are written for an academic audience.
Examples of Scholarly Resources include: Academic journals, books written by experts in a field, and formally published encyclopedias and dictionaries.
Peer-Reviewed Journals: Peer-reviewed journals are evaluated prior to publication by experts in the journal’s subject discipline. This process ensures that the articles published within the journal are academically rigorous and meet the required expectations of an article in that subject discipline.
Empirical Journal Article: This type of scholarly resource is a subset of scholarly articles that reports the original finding of an observational or experimental research study. Common aspects found within an empirical article include: literature review, methodology, results, and discussion.
Adapted from “Evaluating Resources: Defining Scholarly Resources,” located in Research Guides in the GCU Library.
☐ The writer is clearly in command of standard, written, academic English. Utilize writing resources such as Grammarly, LopesWrite report, and ThinkingStorm to check your writing.
