Programming is both an enjoyable and a difficult task. A seemingly small slip can introduce a serious error or create a security vulnerability. The need for, and ...

It is nearly inevitable that bugs will appear in a codebase during software development. To catch these bugs before they lead to real-world consequences, the formal verification community has ...

The propositional satisfiability problem (SAT) was the first to be shown NP-complete by Cook and Levin. SAT remained the embodiment of theoretical worst-case hardness. However, in stark contrast to ...

A team of mathematicians has finally finished off Keller’s conjecture, but not by working it out themselves. Instead, they taught a fleet of computers to do it for them. Keller’s conjecture, posed 90 ...

Intuitionistic logic, i.e. logic without the principle of excluded middle (P ∨ ¬ P P \vee \neg P), is important for many reasons. One is that it arises naturally as the internal logic of toposes and ...
