  1. CS1800 Summer 2014 Overview

  2. The Course Web Site • http://www.ccs.neu.edu/course/cs1800/13F/ • http://www.ccs.neu.edu/course/cs1800/13FHON/ • Make one of these a favorite. • Check the site regularly for announcements. • Send me an email if you think something is wrong. • I’ll try to fix it.

  3. Text • online and at the bookstore: Discrete Structures by Harriet Fell and JavedAslam • and handouts http://www.ccs.neu.edu/course/cs1800/13F/handouts.html

  4. Waiver Exam • Do you think that you know most of the material in this course? • Try the on-line homework to see how much you do know. • Let me know if you would like to take an exam to get out of this course. • If you get the waiver, you will not get course credit but you can take an extra elective.

  5. Why Discrete Structures? • CS and IS are hard --- but rewarding. • They are not just programming --- but programming is very important. • They both involve solving problems with computers. • Most CS departments came out of math or engineering. • Our college was started by 6 math department faculty members.

  6. What do we study in CCIS? • Specific skills (e.g., Perl syntax) • General knowledge (e.g., how to program) • Analytical thinking (e.g., problem solving) • Some CS/IS courses are more heavily weighted toward the top of this list (e.g., course focused on a specific programming language). • Some CS/IS courses are more heavily weighted toward the bottom of this list. • CS1800 is weighted toward the bottom.

  7. CCIS continued • In CCIS, we will teach you how to solve problems with computers.  • You will learn to be rigorous, analytical thinkers and problem solvers.  • If all you learned was Excel syntax, you would be a lousy computer scientist.  Furthermore, when Excel++ comes out (hypothetically), you would be out of a job...

  8. Our goal in CS1800 and CS2500is to teach you • How to *think* • How to *solve* problems (in any language or computational domain) • How to *teach yourself*, • so that when new technologies & techniques become available, you can learn to use them.

  9. Corollary • We will sometimes, if not often, give you problems to solve which we have not specifically told you how to solve (though we will have given you the general techniques).  • This is by design, not by accident.  • You must learn how to "learn on your own.” • What is a corollary?

  10. Consequence • Employers will love you.  • CCIS students are often hired for jobs which seemingly have nothing to do with CCIS courses (e.g., consulting, Wall street financial analysis, etc.).  • Why?  Employers want rigorous, analytical thinkers who can learn and solve problems.

  11. Much of CS and IS is based on mathematics • hardware/circuits • Boolean algebra • programming languages • lambda calculus (Racket) • Turing machines (imperative languages) • algorithmic analysis • proof, combinatorics, etc. • databases • sets and relations

  12. More Math in CS and IS • search engines and information retrieval • probability and statistics • algorithms • graphics and game design • pattern representations • geometric algorithms • bioinformatics • algorithms on sequences and strings • counting and probability

  13. even More Math in CS and IS • big data • statistics, algorithms • networks • graphs and graph algorithms • human computer interaction (HCI) • algorithms • experimental design – statistical analysis
