The Eel Programming Language and Internal Concurrency in Logic Agents

This paper describes work done on creating the logic programming language Eel. Eel is an is an extension of prolog which reserves two predicates to handle i/o, process communication and process initiation. The paper also presents an adaption of a behaviour based agent architecture and gives examples of how parts of that adapted architecture can be implemented in Eel. As an aside the paper comments that the Agent Oriented Programming paradigm currently contains two different metaphors for concurrency. Eel’s event based approach to process communication and process initiation introduces an explicit representation of state to the evaluation of a logic program. The paper demonstrates how Eel can be used for a declarative approach to object states in the examples that show the object oriented implementation of the suggested agent architecture.
