This meeting is part of the Computational Logic Autumn Summit 2022.

Date: 23-24 September 2022

Venue: Tbilisi State University, Chavchavadze ave. 1, 0179 Tbilisi, Georgia, room 202

Registration: Registration is free but mandatory. To attend the workshop, physically or online, please send a mail to Frédéric Blanqui. Connection instructions will be sent to online participants a few days before the event.

If you are interested in giving a talk, please send a mail to Frédéric Blanqui with a title and abstract. We welcome talks, tutorials, demos, on library descriptions or on methodologies, algorithms and tools trying to tackle the challenges raised by the development, maintenance, refactoring and search of large libraries of proofs. We especially welcome talks on search tools.
