Logic & Reasoning

The activity of this group is centered around the logical and mathematical modelling of reasoning, with special attention to mathematical fuzzy logic, uncertainty models, logics for incomplete information and computational argumentation, and the design of efficient algorithms for solving satisfaction and optimization problems by methods based on SAT, constraints and metaheuristics.
