A synchronous backtrack algorithm, a welD-known method for distributed scheduling problems, has difficulties handling (A) rapid schedule adjustments and (B) impartial assignment. Thus, this paper proposes two kinds of heuristics: (1) parallel assignment and (2) multiple priority strategies, and developed the distributed scheduling system which makes use of the heuristics. It consists of schedulers for each power station and mediation agents which have cloning and merging functions to support the implementation of the heuristics. Finally, the result of experiment shows an improvement when handling the rapid adjustment and the impartiality issues with reasonable computational overhead.展开更多

Nowadays in China this artistic revolution has sparked a vivid debate among the art critics on three main topics: (1) definition of the phenomenon; (2) analysis of its nature; and (3) classification of the artistic production. In this article, all these aspects are analysed in order to give a comprehensive view of the present theoretical discussion and of its future development.展开更多
