XE

Resulting from the Exbed project, this general-purpose programming language supports data abstraction and rule-based programming and is based on but is not a formal extension of CLU.

Starlog

Declarative temporal logic programming language for: general purpose programming, simulation, modeling reactive systems. Starlog programs consist of 2 components: a set of timed facts, a set of temporal logic rules. Somewhat like Prolog.

Conferences: Logic-Related

In the last few years, ever more events overlapping in technical scope with LICS (Symposium on Logic in Computer Science) are scheduled with no coordination, often causing conflicts: 1995 LICS and FPCA were at the exact same time and place. This page atte
