Logic and Computation
Over the last few decades, computers have been increasingly used for tasks that were once thought the sole preserve of human intelligence. Scientists have developed ways of formally representing knowledge and using “intelligent” methods to solve problems with the aid of computers. This field is generally described as computational intelligence.

About
Over the last few decades, computers have been increasingly used for tasks that were once thought the sole preserve of human intelligence. Scientists have developed ways of formally representing knowledge and using “intelligent” methods to solve problems with the aid of computers. This field is generally described as computational intelligence.
Logic and Computation focuses on logical methods and algorithms for modeling, constructing, and analyzing complex and intelligent computer systems. The research focus comprises basic research on mathematical logic, automated decision procedures, and algorithms and their complexity, as well as applications of logical methods to data and knowledge bases, semantic systems, artificial intelligence, and formal methods for building and operating computer systems. Logic serves as a unifying theme that provides the theory and tools to acquire, represent, and manipulate information in intelligent systems, and to address challenges such as the security, safety, and correctness of safety-critical and distributed systems.
