  • Analysis Problems in the Models on Social Networks in Marketing

    A model of impact in a social network is a weighted directed graph. Its vertices correspond to the members of a social group, and its arcs describe their mutual impact. A real value (an opinion of the group's member) as a function of time is ascribed to each vertex, and a real number (weight) is ascribed to each arc (a degree of impact of one member of the group to another or, what is the same, a degree of confidence of one member of the group to another). All strong subgroups (non-degenerated strong components of the digraph) develop their final opinions which depend only to the initial opinions of their members. The final opinions of other members of the group are linear convolutions of the final opininions of all strong subgroups. A number of indices is used for the additional quantitative characteristics of the social group. From the marketing point of view, the solution of the analysis problems provides a segmentation of the target audience for the determination of the most appropriate objects of marketing impact (members of the strong subgroups).

  • The internal structure of the affective components of family attitudes

    The work is devoted to one of the indicators of hidden family aggression – emotional components of family attitudes. The research is based on the pilot measurements carried out by the survey using the method of semantic differential. A total of 50 people were interviewed, including 18 men and 32 women, aged 18 to 64 years. The option with calibration was used, and respondents were asked to characterize on a semantic scale the real families and both ideal positive and negative ones. Images of ideal constructs defined in semantic space the scale and direction. In accordance with Coombs's "ideal point" approach, the level of emotional perception was estimated by us from the relative distances from the image of the real object to the images of ideal constructs. Analysis was performed for each respondent separately, and based on the results the distribution functions of emotional perception by respondents were built. They reflected the internal structure of the group for affective components. The calculations were performed in the linear approximation (for half-difference of the above-mentioned relative distances) and within the framework of the non-linear psychosemantic phenomenological model. In the last the levels of perception are given in the form of differential equations, which were solved by the Monte Carlo method with by AnyLogic multi-agent simulation package. The obtained results confirm the earlier estimates based on the averaged data. The average value of the level of emotional perception throughout the study audience is positive (0.33 on a scale from -1 to +1), which indicates the absence of aggressive behavior for the majority of respondents. A strongly negative level (from -0.5 to -1) showed only 6%, against this background, they can develop aggressive behavior. Another 6% are characterized by a slight emotional irritation in the family sphere (the level from -0.1 to -0.3), this is an intermediate group which under adverse conditions can develop into a risk group. For the rest of the study audience (88%) emotional relationships in the family are not aggressive, positive.

  • Synthesis of kinematic surfaces based on elliptic rotation of the plane

    The algorithm of forming of kinematic surfaces with a constant cross-sectional area based on a complex equiaffine transformation of the plane (elliptic rotation) is considered. Functional dependences of elliptic rotation parameters for the formation of a one-parameter family of equiaffine lines on a plane are determined. At the same time the received families of lines can not include the line prototype and the line image at the set constant parameters of rotation. Conditions of receiving the line prototype and the line image at the set parameter of family and the parametrical equations of shift of the geometrical center of a curve are defined. The conditions for the formation of central surfaces are determined. It is established that the surfaces obtained can be periodic. The domains of admissible values of the parameters and functions included in the parametric equations of one-parameter families of curves are determined. It is shown that as a closed loop one can use not only an analytically determined curve, but also a polyline (for example, a polygon). Examples of kinematic surfaces are given.

  • Inaccuracy of branch and bound algorithm

    The aim of the work is to verify the accuracy of the solution of the traveling salesman problem by the method of branches and boundaries with a large difference in the length of the chords of the transport graph. It is considered an NP-hard task. It is proved that the Vig method can not give an optimal result in a transport graph with a large difference in the values of the elements in the cells of the original matrix, when its zero cells will have very different estimates. The reason for the inaccuracy of solving the travelling salesman problem is the inadequacy of the adopted model for the calculation of the original formulation of the problem. It consists in the injustice of the second hypothesis on the evaluation of the zero element in the evaluation matrix included in the optimal route. The hypothesis is accepted without strict proofs and has probabilistic character. The use of the minimum values of the row and column from the matrix is appropriate, as determined by the route of the smallest length. It is doubtful whether it is true that there is always a need to strike out at each stage the zero element with the maximum total score. The reason is that, firstly, it has a random character in General. Secondly, this assessment does not take into account all possible combinations of combinations of branches giving the optimal combination, since their recursion is not carried out. The technique of improving the method of branches and boundaries is proposed, which consists in additional verification of the obtained optimal route by removing the branch with an estimate one step below the maximum at each stage of branching. Numerical experiment is carried out.

  • Improving the static program analysis based on explicit call graph

    The aim of the study is to develop static analysis algorithms, to search for all possible sequences of function calls leading to a certain point in the program. To achieve this goal the explicit call graph is analyzed, in which all possible paths between two vertices are searched. The analysis is carried out in two stages: 1) at the preparatory stage, a new graph is constructed based on the call graph, from which excess vertices and arcs are removed; 2) in the second stage, a search is made in the new graph for possible paths from the root node to the given one. Also this paper provides an experimental comparison of the developed algorithms with the closest analogue, the Yen algorithm.
