Adaptive logics: a parametric approach

Adaptive logics: a parametric approach

Adaptive logics (ALs) in standard format are defined in terms of a monotonic core logic L, a distinct set of ‘abnormal’ formulas and a strategy, which can be either reliability or minimal abnormality. In this article we we ask under which conditions the consequence relation of two ALs that use the same strategy are identical, and when one is a proper subrelation of the other. This results in a ...

The Adaptive Logics Approach to Abduction

A new non-parametric approach for suppliers selection

In this paper we propose a simple non-parametric model for multiple crite-ria supplier selection problem. The proposed model does not generate a zeroweight for a certain criterion and ranks the suppliers without solving the modeln times (one linear programming (LP) for each supplier) and therefore allowsthe manager to get faster results. The methodology is illustrated using anexample.

Hierarchic adaptive logics

This paper discusses the proof theory, semantics and meta-theory of a class of adaptive logics, called hierarchic adaptive logics. Their specific characteristics are illustrated throughout the paper with the use of one exemplary logic HK, an explicans for reasoning with prioritized belief bases. A generic proof theory for these systems is defined, together with a less complex proof theory for a...

A General Characterization of Adaptive Logics∗

This paper contains a unified characterization of adaptive logics. The general structure is presented in the simplest possible guise, both for flat and prioritized adaptive logics. The latter are presented as a special case of combined adaptive logics. The aim of the paper is to provide the general framework underlying several other papers in this volume and to prepare the unified metatheory of...
