Cpfg is a program for simulating and visualizing plant development, based on the theory of L−systems. A special−purpose programming language, used to specify plant models, is ...
This paper addresses the frame problem for programming theories that support both sharing and encapsulation through specification variables. The concept of dynamic frames is introd...
An algorithm is described which computes stable models of propositional logic programs with negation as failure using the Assumption Based Truth Maintenance mechanism. Since stabl...
We report on work in progress regarding a foundation for the notion of meta-variable in logical frameworks and type theories. Our proposal is to treat meta-variables as modal varia...
