Formal Specifications of the MLT Multi-Level Theory
This project includes formal specifications of the Multi-Level Theory (MLT) and its generalization MLT*.
There are two specifications of MLT in order to support the validation and verification of the theory using the Alloy Analyzer (used in ):
- mlt.als - The first specification of MLT, which assumes static classification
- mlt_dynamicclassification.als - A minor extension of MLT, indexing the primitive "instance of" predicate with a world variable w, thereby including support for dynamic classification in MLT.
There is also a specification of MLT* in Alloy comprising the following files (used in ):
- mlt_star.als - The specification of MLT* containing all of its definitions;
- mlt_star_validation.als - The validation of MLT*, containg a series of simulations and constraints that arise from its definitions;
- mlt_theme_clean1.thm - A basic theme for instance visualization;
- mlt_theme_clean2.thm - A cleaner theme for instance visualization.
In addition to the Alloy specifications, a specification in first-order logics in the TPTP syntax is also available, which can be used for automated theorem proving:
- tptp/mlt-star.p - MLT* formalization in TPTP syntax;
- tptp/reports - Reports on automated proofs from System on TPTP.
