    • ALEX - an Alexical Programming Language 

      Kozen, Dexter; Teitelbaum, Tim; Chen, Wilfred Z.; Field, John H.; Pugh, William W.; Vander Zanden, Bradley T. (Cornell University, 1987-05)
      ALEX is an experimental language for high-level parallel programming. It is a testbed for exploring various non-traditional ways of expressing algorithmic ideas, making extensive use of high-resolution color graphics. ...
    • Attribute Grammars in Constraint-based Graphics Systems 

      Barford, Lee Alton; Vander Zanden, Bradley T. (Cornell University, 1987-06)
      A constraint-based graphics system provides a flexible, intuitive framework for describing relationships among graphical objects in applications such as document preparation, font design, and solid modelling. This paper ...
    • A Better Tool for Query Optimization 

      Bitton, Dina; Vander Zanden, Bradley T. (Cornell University, 1985-04)
      When evaluating the performance of a query strategy, one must often estimate the number of distinct values of an attribute in a randomly selected subset of a relation. Most query optimizers compute this estimate based ...
    • A General Framework for Computing Block Accesses 

      Vander Zanden, Bradley T.; Taylor, Howard M.; Bitton, Dina (Cornell University, 1985-12)
      A physical database system design should take account of skewed block access distributions, nonuniformly distributed attribute domains, and dependent attributes. In this paper we derive general formulas for the number ...
    • Incremental Constraint Satisfaction and its Application to Graphical Interfaces 

      Vander Zanden, Bradley T. (Cornell University, 1988-10)
      Software that emphasizes pictures, rather than text, has become increasingly popular since the introduction of the Macintosh computer. Creating this software is a time-consuming task that can take months or years. ...
    • An Incremental Planning Algorithm for Ordering Equations in a Multilinear System of Constraints 

      Vander Zanden, Bradley T. (Cornell University, 1988-04)
      Constraint equations are increasingly being used in interactive applications such as graphics, logical programming, and simulation that demand immediate feedback. To handle the performance requirements imposed by such ...
