We study the problem of finding an anti-Nash equilibrium in bimatrix game using global search algorithm. Finding anti-Nash equilibrium equivalently reduces to a quadratic programming with an indefinite matrix and line...

We consider the minimization problem of an integral functional in a separable Hilbert space with integrand not convex in the control defined on solutions of the controlsystem described by nonlinear evolutionary equat...
This paper studies the problem of algebraic cryptanalysis where state-of-the-art SAT solvers are used to invert some cryptographic function. We define a new metric of the hardness of CNF formulas that encode the corre...

We provide a triple of diagonal Latin squares of order 10 that is the closest to being a triple of mutually orthogonal diagonal Latin squares found so far. It was obtained by constructing all orthogonal mates for diag...

In the article the problem of analysis of the water-dissolved greenhouse gases interchange (CO2 and CH4) through the water surface with atmosphere is considered. We assess the seasonal variation of the gaseous interch...

For a nonlinear parabolic heat equation we construct a heat wave type solution composed of the zero and nonnegative solutions joined continuously along the wave front. We prove the existence and uniqueness of an analy...

The paper describes the main principles of visualization software development, as well as implemented by this software approach, which is based on the use of ontologies to describe both the rendered domain, and the rules of its 3Ddisplaying. This approach allows the user to avoid programming the 3Dscene and describe it in terms of the research area. The paper set out a formal model of a software tool, its architecture, basic modules and ontology structure. The process of visual scene design and creation is described, including the steps of ontology modelling, visual objects creation, formation of scene describing rules, code generation, visualization, organization of data exchange between visualization software and data source. WebGLbased library was chosen as primary means for 3D graphics rendering, which allows to create visual scenes in the user's web browser. Examples of generated scenes and the question of its performance are also discussed in the article.
An algorithm for page layout analysis (segmentation) is suggested in the paper. It allows whitespace between text blocks to be detected on a document page. The algorithm could be used in document analysis and recognit...
