In this paper, we introduce one simple heuristic for value ordering in solving frequency assignment problem. Our approach is based on a special container to organize the values selection by jumping between two sides of domain. In order to reduce the time and space complexities of algorithm, we change the current value selection with last unchecked element in the domain, and put all the inconsistent...
Distributed constraint satisfaction problem (DisCSP) has being become to a new research branch of artificial intelligence. This paper improves the variable selecting strategy in concurrent search. At the same time, a method for dynamic variable ordering which is fit for distributed multi-agent environment is proposed to solve DisCSP, and value support proportion is defined to calculate variable ordering...
As digital resources increasingly growing and the economic benefit of digital intellectual property rights being increasingly important, people has been increasingly emphasis on information security issues brought by the data remnants in storage devices. They try their best to prevent the potential risks. In this paper, we survey comprehensively related technologies, standards and trends of erasure,...
