General Information
The 16h International Workshop on the Implementation of Logics will be held October 25th, 2026 in conjunction with the 26th International Conference on Logic for Programming, Artificial Intelligence and Reasoning on Speces, Greece.
We are looking for contributions describing implementation techniques for and implementations of automated reasoning programs, theorem provers for various logics, logic programming systems, and related technologies. Topics of interest include, but are not limited to:
- Propositional logic and decision procedures, including SMT
- First-order and higher order logics
- Non-classical logics, including modal, temporal, description, non-monotonic reasoning
- Formal foundations for efficient implementation of logics
- Data structures and algorithms for the efficient representation and processing of logical concepts
- Proof/model search organization and heuristics for logical reasoning systems
- Data analysis and machine learning approaches to search control
- Techniques for proof/model search visualization and analysis
- Practical constraint handling
- Reasoning with ontologies and other large theories
- Implementation of efficient theorem provers and model finders for different logics
- System descriptions of logical reasoning systems
- Issues of reliability, witness generation, and witness verification
- Evaluation and benchmarking of provers and other logic-based systems
- I/O standards and communication between reasoning systems
We are particularly interested in contributions that help the community to understand how to build useful and powerful reasoning systems, and how to apply them in practice.
