Main Objectives
• Learn how to think algorithmically.• Get LOTS of practice programming.• Take a tour of computer science.• Learn a lot of C, a little C++, and some Unix.
What is Computer Scienceand Engineering?
Conventional(but unsatisfying) definitions:
• Computer science is the study of software, and is closest to the field of mathematics.
• Computer engineering is the study of hardware and is closest to the field of EE.
CSE is Engineering(Both software and hardware)
CSE is Art
CSE is Invention
CSE is Logic and Mathematics
The Minimax Algorithm
Quicksort P = NP?The PageRank Algorithm
Computing is a Mode of ScienceTheory Experiment
Simulation via Computation
CSE is a Craft to be Learned
Learning the Craft of Programming• Write programs for fun!• Write programs for work.• Write programs for contests.• Learn several languages:
– An assembly language. (x86, MIPS, PowerPC)– A procedural language (C, FORTRAN)– An object-oriented language (Java, C#)– A scripting language (python, perl, bash)– A functional language (LISP, Haskell)
• Work on a team writing software (classes, research)• Download, examine, and modify open source software.• Read good books about computing.• Revisit programs you have written before.
