Here is a list of open problems and challenges in K and matching logic, in no particular order. While we are doing our best to keep this list actual, it may well be the case that some of the problems have been solved in the meanwhile or that we have found a different way to approach the problem. In case you are interested in working on any of these problems, please send us a note at (email@example.com) to make sure that the problem is still actual and nobody is already working on it. If you are not part of our team already and would like to be or to collaborate with us, please let us know.
Dynamic matching logic.
Currently (Jan 2016), we are framing matching logic as a static logic, that is, as one for reasoning about program configurations at a particular place in the execution of a program:

- Coinductive program verification.
- True concurrency with K.
- Rewrite-based parsing.
- Fast execution engine for K.
- Semantics-based compilation.
- Semantics-based test-case generation.
- Language-independent symbolic execution framework.
- Language-independent infrastructure for program equivalence.
- Strategy language.
- Systematic comparison of K with other operational approaches. K evolved from other approaches, systematically analyzing their advantages and disadvantages, and keeping the advantages and eliminating the disadvantages. This is partly explained in my book draft, but it needs to be also published as a conference/journal paper, for wider dissemination. Indeed, we have encountered many scientists who seem to think that K is some new theoretical development based on new principles. Well, sorry to disappoint, but K is an engineering endeavor attempting to get the best of the ideas developed by the formal semantics community over the last four decades, avoiding their limitations. The main novelties of K, besides its unique notation, are: (1) its concurrent semantics, which allows for true concurrency even in the presence of sharing; and (2) its configuration abstraction mechanism which is the key for more modular language definitions.
- Configuration abstraction.
- Defining/Implementing language translators/compilers in K. Either in translation-validation style or provably correct.
