Welcome to CSE 105! All class members are asked to read the information on this webpage and check it frequently for updates.
Section ID Number: 503693
Henceforth, announcements will be posted on the discussion board only. [Posted on July 9, 2004 at 1:06 PM]
This course introduces the basic, formal ideas underlying the notion of computation: finite automata, regular expressions, context-free grammars, pushdown automata, Turing machines, computability, decidability, undecidability, the halting problem, and reducibility. In studying these objects and concepts, we aim to determine what can and cannot be computed, and on which type of computational model. The course stresses the understanding of the basic concepts and constructions.
This material is essential to being a computer scientist or computer engineer. The course provides tools to understand some fundamental properties of hardware and software. We will be studying basic theoretical problems that have importance in practice and direct application to fields such as Programming Languages, Compilers, Artificial Intelligence, VLSI CAD, Computer Graphics, and Cryptography! (Adriana's research area).
The course involves mathematical abstraction and proofs. One of the most important components is learning to deal with these. This will promote the development of abilities that are extremely valuable to professionals in any area of Computer Science and Computer Engineering: the ability to think in an organized fashion, solve problems, know when a problem cannot be solved, know when you have not solved a problem, and express yourself clearly and precisely.
Do not let the formal nature of the material daunt you. Programming is formal too. You just need to learn the "rules" of the formal systems we will study, just like you learn the "rules" of Java or C.
|The general goals of this course are the following.|
|Upon completion of the course, the student should have the ability to perform the following tasks.|
and any of the following:
More specifically, prerequisite topics include discrete mathematics: exposure to relations, set notation and graphs; programming in some standard imperative language; elementary logic and predicate calculus, boolean functions and truth tables.
Note: Credit not offered for both Math 166 and CSE 105. Equivalent to Math 166.

Make use of the discussion sections and staff office hours to ask questions about course material. For matters of a personal nature, students may email the staff directly. Avoid using email for technical questions. Instead, use the Web-based discussion board, so that all students can benefit from the staff's responses.
This excellent book is available at the UCSD campus bookstore (new: $102.35, used: $76.80) and elsewhere. You may want to use addall.com to compare online prices. It is also on reserve in the UCSD Science & Engineering Library.

|Problems:||PS 1: pdf, ps||PS 2: pdf, ps||PS 3: pdf, ps|
|Solutions:||SS 1: pdf, ps||SS 2: pdf, ps||SS 3: pdf, ps|
These problem set solutions and the exam solutions available below tell you not only how to solve the problems, but also how to formulate your answers. You are encouraged to read the solution to a problem, even if you know how to solve it or you got it right on an exam, because this will help you improve your writing skills.
The two tests will take place in the lecture room during regular lecture hours on the dates specified in the course schedule. The topics covered on each of these tests will be announced in class and on this webpage. The final examination will take place on the date specified in the course schedule. It will be inclusive of all course material. All exams are closed book and notes. Calculators may not be used. For each exam, all needed paper will be provided with the exam itself. Please bring a photo ID to every exam.
Make-up exams will not be offered. The only acceptable reason to miss a test is that the student has a certified health problem at the time. For a student with such a medical excuse, arrangements will be made to shift the weight of the test to the final examination. A student who misses the final exam, will obtain a zero (0) on it. If there is any foreseeable reason for which you cannot take the final examination at the scheduled time, then please do not take the course.
If a student is approved as having legitimately missed a test, then a score for that test will be computed as a function of 1) the score the student obtained on the final examination, 2) the statistical parameters of the test, and 3) the statistical parameters of the final examination. This function is complex and cannot be detailed in advance.
