The method of definition of cliques fuzzy set is proposed and justified. This method is an extension of the Maghout method for the crisp graphs. The example of definition of cliques fuzzy set is considered. An estimation of degree isomorphism of fuzzy graphs is shown on the basis of their ...
I am sure that it is possible, under standard assumptions, to construct an artificial problem L in NP that is in average-case-P according to Levin’s definition but not in P. Such a problem would not be polynomial time solvable, but it would be easy to solve on average under any samp...
Definition Let V and W be vector spaces. Then V is isomorphic to W, denoted V≅W, if and only if there exists an isomorphism L: V→W. If V≅W, there is some isomorphism L: V→W. Then by Theorem 5.14, L−1: W→V is also an isomorphism, so W≅V. Hence, we usually ...

However, a multilayer network may represent an exception if its own objects consists of heterogeneous entities, as the heterophily will be essential for the definition of the interlayer edges and cannot be omitted in the similarity analysis; by extension, the same issue concerns heterogeneous ...
We have tried several natural cell decom- position definitions, but none of them have the properties that the cell decomposition is finite and that it determines the point visibility graph. For example, we could extend our definition of the cell decomposition of a spiral polygon to the cell ...
Definition 2.1. (Measurable spaces) A measurable space (X, X ) is • separable if X contains all singletons in X ; • countably separated if there exists a countable family of sets in X separating points in X ; • countably generated if there exists a countable family of sets ...
Based on the definition of subgraph isomorphism, we can give the definition of a frequent subgraph mining as follows. Definition 21: Frequent subgraph mining for composite service. Given a composite service graph dataset D = {G1, G2,…, Gn}, and a minimum support min_sup, assume sup(g)...
Then, by definition, X=⋃i=0k−1Xi. Let w=w1…w3k−1 be an arbitrary vertex whose underlying string is in Xi. It then follows that wk+1…w2k−1=0i1k−i−1, and so Xj∩Xℓ=0̸ holds for all j≠ℓ. Since |Xi|=2k−1, we have |X|=k2k−1. With a para...
