Two approaches to low-parametric SimRank computation

Egor P. Berezin, Robert T. Zaks, German Z. Alekhin +2

In this work, we discuss low-parametric approaches for approximating SimRank matrices, which estimate the similarity between pairs of nodes in a graph. Although SimRank matrices an…

Numerical solution of Smoluchowski coagulation equation combined with Ostwald ripening

Robert T. Zaks, Sergey A. Matveev, Margarita A. Nikishina +1

The processes of simultaneous coagulation and Ostwald ripening of particles in the concluding stage of phase transformation are considered. We solve the integro-differential system…

Mosaic-skeleton approximation is all you need for Smoluchowski equations

Roman R. Dyachenko, Sergey A. Matveev, Bulat I. Valiakhmetov

In this work we demonstrate a surprising way of exploitation of the mosaic--skeleton approximations for efficient numerical solving of aggregation equations with many applied kinet…
