Course Highlights

This course features a full set of homework assignments. In addition, the recitation section includes many practice problems. 6.045J is a course in the department's "Theoretical Computer Science" concentration.

Course Description

This course is offered to undergraduates and introduces basic mathematical models of computation and the finite representation of infinite objects. The course is slower paced than 6.840J/18.404J. Topics covered include: finite automata and regular languages, context-free languages, Turing machines, partial recursive functions, Church's Thesis, undecidability, reducibility and completeness, time complexity and NP-completeness, probabilistic computation, and interactive proof systems.
