We analyze a class of imitation dynamics with mutations for games with any …nite number of actions, and give conditions for the selection of a unique equilibrium as the mutation rate becomes small and the population becomes large. Our results cover the multiple-action extensions of the aspiration-andimitation process of Binmore and Samuelson [3] and the related processes proposed by Benaïm and ...

The traditional link analysis algorithms exploit the context information inherent in the hyperlink structure of the Web, with the premise being that a link from page A to page B denotes an endorsement of the quality of B. The exemplary PageRank algorithm weighs backlinks with a random surfer model; Kleinberg’s HITS algorithm promotes the use of hubs and authorities over a base set ; Lempel and ...

In the continuous and rapid growth that the technology has, people are all engaged, even without realizing it, the important thing is to exploit all the advantages that it gives to them. In these times much is what it has been said about the knowledge society and collaborative work, in this sense some project have been set up to benefit the most needy. In Venezuela such networks are coming with...

We consider several distances between two sets of points, which are modifications of the Hausdorff metric, and apply them to describe some fractals such as δ-quasi-self-similar sets, and some other geometric notions in Euclidean space, such as tilings with quasi-prototiles and patterns with quasi-motifs. For the δ-quasi-self-similar sets satisfying the open set condition we obtain the same resu...
