======Software Specification and Verification, Fall 2020======
This is an introductory course on formal software specification and verification, covering various formalisms, methods, and tools for specifying the properties of a software program and for verifying that the program meets its specification. Its goal is to acquaint the students with fundamentals of formal software verification and to prepare them for conducting research in the area. We will focus on deductive (theorem proving) methods. A separate, complementary course entitled "Automatic Verification" covers algorithmic (model checking) methods.
