The traditional method of pairwise job interchange compares the cost of sequences that differ only in the interchange of two jobs. It assumes that either there are no intermediate jobs (adjacent pairwise interchange) or that the interchange can be performed no matter what the intermediate jobs are ( nonadjacent pairwise interchange). We introduce a generalization that permits the pairwise inter...

As a recommendation of the W3C (WWW Consortium), RIF (Rule Interchange Format) is dedicated to rule interchange between different rule languages. To be a general rule interchange format, RIF should first support rule interchange with SWRL (Semantic Web Rule Language), RuleML (Rule Markup Language), R2ML (REWERSE R...
