You have been invited to the following event.

Title: The CakeML project and liveness proofs for non-terminating programs
Speaker: Magnus Myreen


Abstract:

There are useful programs that do not terminate, and yet standard Hoare  
logics are not able to prove liveness properties for non-terminating  
programs.

This talk has two parts. The first part provides a general overview of the  
CakeML project, which aims to develop a realistic verified ML compiler. The  
project is known for being the first to successfully bootstrap a verified  
compiler.

The second part of the talk is based on an up-coming ITP paper. The second  
part describes how a Hoare-like programming logic (Characteristic Formulae)  
for CakeML programs has been extended to enable reasoning about the I/O  
behaviour of programs that do not terminate. The approach avoids  
co-induction in order to not require productivity of non-terminating loops.

CakeML is an open source project https://cakeml.org/
