Introduction to Computational Theory
Computational theory is a fundamental area of computer science that focuses on the limits of what can be computed, and how efficiently it can be done. The field is vast and includes various subfields such as automata theory, complexity theory, and algorithmic information theory.
Key Concepts
- Turing Machines: An abstract machine that manipulates symbols according to a set of rules. It is used to simulate the logic of any computer algorithm.
- P vs NP Problem: A major unsolved problem in computer science, questioning whether every problem for which a solution can be verified quickly can also be solved quickly.
- Church-Turing Thesis: A hypothesis about the nature of computable functions, proposing that anything that can be computed can be done so using a Turing machine.
