Commit Message

Implementation for learning MMLTs, new model for collecting statistics (#153)

* Made RowImpl public to enable access in custom observation table implementations.

* Made several methods of RowImpl public, to enable external access from observation tables that are defined in the learner module.

* Started with integration of MMLT.

* Extended EquivalenceOracle.java with LocalTimerMealyEquivalenceOracle.

* Created module for symbol filters; added tests for counterexample handling for MMLT learner.

* Functions for printing stats as JSON/YAML.

* Renamed statsContainer; exporting mmlt caches.

* Included symbol-filters module in dependency management.

* Renamed fast cache to cache for MMLTs; added integration tests for MMLTs; allow access to stats during testing of learner.

* Added more test models for the MMLT learner.

* Added more test models for the MMLT learner.

* Added cache consistency test for MMLT learning.

* Removed location type parameter from LocalTimerMealyEquivalenceOracle.

* Cache for MMLTs now inherits LearningCache

* Multiple EQ tests for MMLTs can now respect the provided list of inputs for counterexamples.

* Added tests for the cache; cleaned-up some files.

* Added tests for the MMLT cache consistency test.

* Made the MMLT SUL an interface with default methods.

* Made symbol filters more independent from MMLTs

* StatisticsSymbolFilter has stats container as constructor parameter.

* Moved several MMLT examples to test-support.

* Added an example for learning MMLTs; added module info for symbol filter module.

* Added an example for learning MMLTs; added module info for symbol filter module.

* Added more descriptions for included MMLT models

* More info on model params

* Updated reset search oracle to check if it can return a counterexample with the provided inputs.

* adjust to AutomataLib refactorings

* adjust to AutomataLib refactorings

* adjust to AutomataLib refactorings

* Using correct function to render MMLT i... (continued)
