this paper examines critically the contributions of cournot, jevons and walras as the founders of classical mathematical economics from a methodological standpoint. advances in different economic schools and doctrines in the 19th century produced an environment of multi-dimensionality in economic analysis which was regarded by the pioneers of classical mathematical economists as a chaotic state...

Existing set-term matching algorithms [l] for logic-based database languages, of which set terms have the commutative and idempotent properties, have several problems: Given a pair of set terms, matchers can only be computed uequentiollyand duplicatedmatchers are generated. Hence, these algorithms cannot take the advantage of existing multiple processors for computing all matchers in parallel. ...

Logic Programs with Ordered Disjunction (LPODs) extend classical logic programs the capability of expressing alternatives decreasing degrees preference in heads program rules. Despite fact that operational meaning ordered disjunction is clear, there exists an important open issue regarding its semantics. In particular, does not exist a purely model-theoretic approach for determining most prefer...
