11th International Workshop on the Implementation of Logics


The 11th International Workshop on the Implementation of Logics will be held in November 2015 in conjunction with the 20th International Conference on Logic for Programming, Artificial Intelligence, and Reasoning, at the Laucla Bay Campus of the University of the South Pacific in Suva, Fiji.

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:

  1. Propositional logic and decision procedures, including SMT

  2. First-order and higher order logics

  3. Non-classical logics, including modal, temporal, description, non-monotonic reasoning

  4. Formal foundations for efficient implementation of logics

  5. Data structures and algorithms for the efficient representation and processing of logical concepts

  6. Proof/model search organization and heuristics for logical reasoning systems

  7. Data analysis and machine learning approaches to search control

  8. Techniques for proof/model search visualization and analysis

  9. Practical constraint handling

  10. Reasoning with ontologies and other large theories

  11. Implementation of efficient theorem provers and model finders for different logics

  12. System descriptions of logical reasoning systems

  13. Issues of reliability, witness generation, and  witness verification

  14. Evaluation and benchmarking of provers and other logic-based systems

  15. 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.

Researchers interested in participating are invited to submit a position statement (2 pages), a short paper (up to 5 pages), or a full papers (up to 15 pages) via the EasyChair page for IWIL-2015.

Submissions will be refereed by the program committee, which will select a balanced program of high-quality contributions.

Submissions should be in standard-conforming PDF. Final versions will be required to be submitted in LaTeX using the easychair.cls class file. Proceedings will be published as EasyChair Proceedings.

If number and quality of the submissions warrant it, we plan to produce a special issue of a recognized journal on the topic of the workshop.


  1. Preliminary proceedings (4.5 MB PDF)

  2. The final proceedings are published as volume 40 of EPiC Computing
