    Deriving Parallel Codes via Invariants

    Systematic parallelization of sequential programs remains a major challenge in parallel computing. Traditional approaches using program schemes tend to be narrower in scope, as the properties which enable para...

    Generation of Efficient Programs for Solving Maximum Multi-marking Problems

    Program generation has seen an important role in a wide range of software development processes, where effective calculation rules are critical. In this paper, we propose a more general calculation rule for ge...

    Toward Bidirectionalization of ATL with GRoundTram

    ATL is a language for describing model transformations currently in uni-direction. In our previous work we have shown that transformations of graph structures given in some form can be bidirectionalized and ha...
