[ Lectures] [Homework]
Basic primitives and paradigms
of rigorous (formal, mathematical) methods
essential in all aspects of computer science.
Tentative list of topics:
Elements of Logic, in particular as they apply to Computer Science.
Fundamental Proof Techniques (Direct proofs and Reductions, Invariants, Proofs by Contradiction, Exhaustive Case Analysis, Existential/Non-Constructive Proofs) with many examples arising in Computer Science.
Induction and Recursion, with emphasis on the Design and Analysis of Data Structures and Algorithms.
Functions and Order of Growth, with emphasis on their relevance in Quantifying Computational Resources (such as time, space and communication).
Elements of Probability and Statistics, with emphasis on very efficient estimation and prediction, especially over massive data sets.
Paradigms from Graph Theory and their applications in fundamental Modeling and Problem Solving.
Elements of Formal Models in Computation: Grammars as building blocks of Programming Languages (and Recursion revisited). The notion of Universal Computational Models (e.g. Turing machines). The Limits of Computability exposed by Diagonalization and analogies with Countable versus Uncountable Sets.
Basics of Number Theory related to Arithmetic over Large Integers and Modern Cryprography.
Tue-Thu 1:30-3:00, KACB (Klaus) 1443.
The material covered in each lecture together with references and/or notes will be posted in the Lectures web page, within reasonable time, and certainly before the homework referring to a particular lecture is due. It is very important to understand that lecture notes are outlines and not substitutes for attending the class or for assigned reading material. from the lecture.
Office hours: Wed 9-11 and 1-2, Klaus 2138, or by appointment.
All email concerning this course should have a subject entitled CS1050.
Your professor welcomes technical and administrative questions and concerns,
and particularly invites your comments (positive and negative) about the class,
including new ideas, suggestions, pointers to related materials (such as readings, web sites, etc),
topics that interest you and you want to explore further (topics that you see no point why you should bother...), and so on.

Weekly or biweekly homeworks, posted in the Announcement Section below
and in the Homework web page (we shall drop the lowest 2 grades): 33.33%.
You may collaborate or read any resource you want in solving the problems, but please indicate your collaboration group and/or the resources you used. You MUST write your answers by yourselves, without any collaboration and without using any resource, as if you are taking a test.
Academic conduct is subject to the Georgia Tech Honor Code.
Complete solutions will be always posted on Homework web page shortly after the deadline.
Late homework policy: no credit for late homeworks.
Finally, please be respectful to your professor and your TAs by using your best handwriting when writing up your solutions (or otherwise type them up). We cannot guarantee that we will read and grade illegible or very tiny handwritings.
Three to Four quizes: 33.33%.
First quiz is Tuesday September 23.
Academic conduct is subject to the Georgia Tech Honor Code
You are responsible for reading these announcements at the end of the day every Tuesday and Thursday.
Tue Aug 19:
is now posted and due this coming Thu Aug 21.
The purpose of this homework is to get to know a little bit about you,
and to get a rough feeling of your current mathematical background.
This Homework 0 is mandatory, but your grade will be either 100
(if you put a descent effort in either answering the questions,
or explaining what background you think you are missing in the
case where you cannot answer a particular question or questions),
or zero (if you do not hand in the homework, or if you clearly
put no time or effort).
Only for this particular homework, please asnwer it without collaborating
with others, and use as few external references or other resources
as possible. In any case, if you use external references or other resources,
please do list them. Try to complete the entire homework in no more than
2 hours. In any case, please write how long it took you to
complete the homework.
