Abstract
In this paper, a number of existing solutions and suggestions towards combining the object-oriented (OO) and logic programming paradigms have been briefly studied and categorized, and a sketch of a new solution has been proposed which tries to capture the essence of OO in terms of modal logic, and which could be implemented as a modal logic programming system.
The proposal is based on the belief that two orthogonal dimensions — object hierarchy and time — are involved in OO that in many respects are similar. For the one-dimensional (static) case, three logics — MU, MU′, and MU″ — have been designed, each allowing a different variety of inheritance modes. The two-dimensional (dynamic) case has been treated in a logic 2MU and its corresponding variants. Under certain OO-motivated definitions of Horn clause, the resolution calculi of these logics turn out to be complete.
The research reported in this paper was carried out at The Norwegian Institute of Technology (NTH) in Trondheim while holding a scholarship of the International Department of NTH.
