Easy Sets and Hard Certificate Schemes1
نویسندگان
چکیده
Can easy sets only have easy certificate schemes? In this paper, we study the class of sets that, for all NP certificate schemes (i.e., NP machines), always have easy acceptance certificates (i.e., accepting paths) that can be computed in polynomial time. We also study the class of sets that, for all NP certificate schemes, infinitely often have easy acceptance certificates. We give structural conditions that control the size of these classes.

متن کاملExperimental Identification of Hard Data Sets for Classification and Feature Selection Methods with Insights on Method Selection
The paper first reports an experimentally identified list of benchmark data sets that are hard for representative classification and feature selection methods. This was done after systematically evaluating a total of 54 combinations of methods, involving nine state-of-the-art classification algorithms and six commonly used feature selection methods, on 129 data sets from the UCI repository (som...
متن کاملPredictive preemptive certificate transfer in Cluster-Based Certificate Chain
Mobile ad hoc networks are a set of nodes that cooperate and communicate wirelessly. This kind of networks in easy to deploy because there is no need of any pre-existing infrastructure. Security in MANETs is a very important issue and it is hard to use conventional security techniques. Many approaches have been proposed to secure communication in MANETs; most of them are based of public-key cer...
متن کاملThe disutility of the hard-easy effect in choice confidence.
A common finding in confidence research is the hard-easy effect, in which judges exhibit greater overconfidence for more difficult sets of questions. Many explanations have been advanced for the hard-easy effect, including systematic cognitive mechanisms, experimenter bias, random error, and statistical artifact. In this article, I mathematically derive necessary and sufficient conditions for o...
متن کاملE-Learning Certificate Using Digital Watermarking Technology
There has been an increasing demand for e-learning technologies and especially for digital watermarking. Using the digital watermarking technology in e-learning is increasingly becoming an important part of the strategy for trusting on-line materials and activities, especially the on-line certificate both easy and cheaply in flexible e-learning way. This paper sets out to develop and create a n...
