Mathematics for Computer Science (4)A basic introduction to Calculus and Linear Algebra. The goal is to make students mathematically literate in preparation for studying a scientific/engineering discipline. The first week covers differential calculus: graphing functions, limits, derivatives, and applying differentiation to realworld problems, such as maximization and rates of change. The second week covers integral calculus: sums, integration, areas under curves and computing volumes. This is not meant to be a comprehensive calculus course, but rather an introduction to the fundamental concepts. The third and fourth weeks introduce some basic linear algebra: vector spaces, linear transformations, matrices, matrix operations, and diagonalization. The emphasis will be on using the results, not on their proofs. Text: Quick Calculus, 2nd Edition, by Kleppner and Ramsey. Matrices and Transformations, Pettofrezzo. Reference: Calculus with Analytic Geometry, Simmons. Introduction to Linear Algebra, by Strang, Requirements: Four exams and 17 assignments Structure and Interpretation of Computer Program (4)An introduction to programming and the power of abstraction, using Abelson and Sussman's classic textbook of the same name. Key concepts include: building abstractions, computational processes, higherorder procedures, compound data, data abstractions, controlling interactions, generic operations, selfdescribing data, message passing, streams and infinite data structures, metalinguistic abstraction, interpretation of programming languages, machine model, compilation, and embedded languages. Text: Structure and Interpretation of Computer Programs, Abelson and Sussman Reference: Simply Scheme, Harvey and Wright. Requirements: Three exams and nine problem sets. Discrete Mathematics and Probability (4)This course covered the mathematical topics most directly related to computer science. Topics included: logic, relations, functions, basic set theory, countability and counting arguments, proof techniques, mathematical induction, graph theory, combinatorics, discrete probability, recursion, recurrence relations, and number theory. Emphasis will be placed on providing a context for the application of the mathematics within computer science. The analysis of algorithms requires the ability to count the number of operations in an algorithm. Recursive algorithms in particular depend on the solution to a recurrence equation, and a proof of correctness by mathematical induction. The design of a digital circuit requires the knowledge of Boolean algebra. Software engineering uses sets, graphs, trees and other data structures. Number theory is at the heart of secure messaging systems and cryptography. Logic is used in AI research in theorem proving and in database query systems. Proofs by induction and the more general notions of mathematical proof are ubiquitous in theory of computation, compiler design and formal grammars. Probabilistic notions crop up in architectural tradeoffs in hardware design. Text: Discrete Mathematics and its Applications, Rosen. Reference: Concrete Mathematics, Graham, Knuth and Patashnik Requirements: Four exams, seven problem sets, one research problem set. How Computers Work (3)Includes the basics of digital logical design, computer organization and architecture including assembly language, processor design, memory hierarchies and pipelining. Students examine the detailed construction of a very simple computer. Problem sets use BetaSim, a RISC simulator written by Mike Wessler. A higher level view of a modern RISC architecture is studied, using the Patterson and Hennessey introductory text, from both the programmer's point of view and the hardware designer's point of view. The distinction between RISC and CISC architectures is emphasized. Text: Computer Organization and Design, Patterson and Hennessey. Requirements: Two exams and four problem sets. Objectoriented Program Design and Software Engineering (4)The concepts of the Objectoriented paradigm using Java. The basic principles of software engineering are emphasized. We study how to design and think in an object oriented fashion. As a final project, students work in groups to develop a Gnutella distributed musicsharing client. Text: Core Java I and II, Hortsmann and Cornell. Requirements: One exam, two problem sets, one project. Algorithms (4)The design of algorithms is studied, according to methodology and application. Methodologies include: divide and conquer, dynamic programming, and greedy strategies. Applications involve: sorting, ordering and searching, graph algorithms, geometric algorithms, mathematical (number theory, algebra and linear algebra) algorithms, and string matching algorithms. Analysis of algorithms is studied  worst case, average case, and amortized  with an emphasis on the close connection between the time complexity of an algorithm and the underlying data structures. NPCompleteness theory is examined along with methods of coping with intractability, such as approximation and probabilistic algorithms. Text: Introduction to Algorithms, Cormen, Rivest, Leiserson. Reference: Computers and Intractability, Garey and Johnson Requirements: Two exams, six problem sets. Systems (3)Topics on the engineering of computer software and hardware systems: techniques for controlling complexity, system infrastructure, networks and distributed systems, atomicity and coordination of parallel activities, recovery and reliability, privacy of information, impact of computer systems on society. Case studies of working systems and outside reading in the current literature provide comparisons and contrasts. The group project is to write an NSF systems proposal to fund a middleware product, for announcement RFP0163. Text: Distributed Systems, Coulouris, Dollimore, Kindberg. The Mythical ManMonth, Brooks. Selected papers. Requirements: One exam, eight essays, one project. Software Engineering for Web Applications (4)Teaches basics of designing a dynamic web site with a database back end, including scripting languages, cookies, SQL, and HTML with the goal of building such a site as the main (group) project Emphasizes computerhuman interface and the graphical display of information. Crucial to the project is the identification of a client with whom the group must work with throughout the month, designing specifications, implementing them, reviewing and evaluating, and testing. This is a reallife client who intends to host the site for the purposes of building a community. Text: Philip and Alex's Guide to Web Publishing, P. Greenspun. Lecture notes, ORACLE reference. Requirements: Three problem sets, one project. The Theory of Computation (3)A theoretical treatment of what can be computed and how fast it can be done. Applications to compilers, string searching, and control circuit design will be discussed. The hierarchy of finite state machines, pushdown machines, context free grammars and Turing machines will be analyzed, along with their variations. The notions of decidability, complexity theory and a complete discussion of NPComplete problems round out the course. Text: Introduction to the Theory of Computation, Michael Sipser.

Banzai AI (1)An quick overview of AI from both the technical and the philosophical points of view. Topics discussed include search, A*, Knowledge Representation, Neural Nets. Text: Artificial Intelligence, Patrick Winston. Selected papers. Requirements: Two problem sets. Unix Workshop (1)A selfstudy workshop to review and/or learn a wide range of Unix tools, including shell scripts, awk, lex, yacc, grep etc. This course did not give grades. It was strictly pass or incomplete. Text: Various online references. Requirements: Two problem sets. Database Management Systems (3)Ravi Jasuja A more formal approach to Relational Database Management Systems, compared the way they were covered during Web Applications. Database systems are discussed from the physical layer of Btrees and file servers to the abstract layer of relational design. Also includes alternative and generic approaches to database design and database management system including relational, objectrelational, and objectoriented systems, SQL standards, algebraic query languages, integrity constraints, triggers, functional dependencies, and normal forms. Other topics include tuning database transactions, security from the application perspective, and data warehousing. Text: Database Management Systems, Ramakrishnan and Gehrke. Requirements: Two exams, 10 assignments, one project. Applied Probability (2)Focuses on modeling, quantification, and analysis of uncertainty by teaching random variables, simple random processes and their probability distributions, Markov processes, limit theorems, elements of statistical inference, and decision making under uncertainty. This course extends the discrete probability learned in the discrete math class. It focuses on actual applications, and places little emphasis on proofs. A problem set based on identifying tumors using MRI (Magnetic Resonance Imaging) is done using Matlab. Text: Fundamentals of Applied Probability Theory, Al Drake.
