In the city of Kurt Gödel, Ludwig Wittgenstein, and the Vienna Circle, mathematical logic and its application to the sciences have a long and rich tradition.
The Vienna Center for Logic and Algorithms at Vienna University of Technology (VCLA at TU Wien) represents six research groups building on the aforementioned work in a wide range of disciplines, including computer science, mathematics, artificial intelligence, philosophy, linguistics, and many more.
