The PolicyUpdater1 system is a fully-implemented access control system that provides policy evaluations as well as dynamic policy updates. These functions are achieved by the use o...
We describe a uniform technique for representing both sensory data and the attentional state of an agent using a subset of modal logic with indexicals. The resulting representatio...
Higher-order narrowing is a general method for higher-order equational reasoning and serves for instance as the foundation for the integration of functional and logic programming. ...
We have implemented parallelism primitives that permit an ACL2 programmer to parallelize execution of ACL2 functions. We (1) introduce logical definitions for these primitives, (...
A classical higher-order logic PFsub of partial functions is defined. The logic extends a version of Farmer's logic PF by enriching the type system of the logic with subset ty...
