Various statistical scheduling methods have been proposed to resolve this problem; however, they are static and cannot easily cope with events in the real world.

Massimo Papi,Ersilia Fiscarellid for efficient querying of large amounts of data, usually represented using RDF. We focus on optimizing a special class of SPARQL queries, the so-called RDF chain queries. For this purpose, we devise a genetic algorithm called RCQ-GA that determines the order in which joins need to be performed for
