一、課程說明 (Course Description)--modified from Chapter 0 of our text book
This course will focus on the traditionally central areas of the theory of
computation: automata, computability, and complexity.
1. The automata theory studies the definitions and properties of models of
computation. These models are used in several applied areas of computer
science. E.g., the finite automaton model is used in text processing,
compilers, and hardware design; the context-free grammar model is used
in programming languages.
2. The computability theory studies how to classify problems that are
solvable by computers and problems that are not solvable. The theory
arises from the discovery that certain basic problems cannot be solved
by computers. (The discovery was made during the first half of the 20th
century, by mathematicians such as Gödel, Turing, and Church.)
3. The complexity theory tries to classify, among problems that are solvable
by computers, which problems are hard to solve (e.g., time-table
scheduling) and which problems are easy (e.g., sorting a list of numbers).
The question --- what makes a problem computationally hard and others
easy --- has been intensively research for the past 35 years. Complexity
theory affects directly the field of cryptography, for it pinpoints
problems that are hard to solve, which consequently leads to the design
of new codes that are hard to break.
In this course, we will introduce some of the fundamental results in each
of the above areas.
