## Models of Computation

This is a 2nd year MEng compulsory course at the Department of Computing, Imperial College London. The course focuses on teaching students the fundamental skills involved in dealing with abstract systems and constructing proofs, through both teaching and exercises.

#### Description of the Course

This course provides a whirlwind tour of some of the key concepts in theoretical computer science. In particular, we will study formal descriptions (models) of computational behaviour.
