Theory of Computing (2024)

In this course we will take a look at various formal computing models. They enable us to classify languages based on their “difficulty”. We will also see how the theory is applied to various fields like compiler design.

The lectures will be on J1 and J2 slots in hall 10/201. The tutorial will be on I2 in hall 1/102.
