    Server-Side Computation of Package Dependencies in Package-Management Systems

    Package managers are often used in recent software development to obtain directly-dependent packages recursively. Typically, package managers make requests to the package registry more than once when computing...

    An approach to completing variable names for implicitly typed functional languages

    This paper presents an approach to completing variable names when writing programs in an implicitly typed functional language. As a first step toward develo** practical systems, we considered a simple case: ...

    Marker-Directed Optimization of UnCAL Graph Transformations

    Buneman et al. proposed a graph algebra called UnCAL (Unstructured CALculus) for compositional graph transformations based on structural recursion, and we have recently applied to model transformations. The co...

    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...

    Maximum Marking Problems with Accumulative Weight Functions

    We present a new derivation of efficient algorithms for a class of optimization problems called maximum marking problems. We extend the class of weight functions used in the specification to allow for weight f...

    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...
