Such graphs are used in network theory as mathematical models of real large networks with millions of elements (for example, social, telecommunicational, financial and other networks). End degrees of randomly selected arc, i.e. the degrees of its two incident vertices, are considered. Two-dimensional probability distribution of end arc degrees is determined. The equations for changes of the named two-dimensional distribution during the graph growth are derived. Final probability distribution of end arc degrees is found. Arc degrees probability distributions for two real large network models are investigated. The obtained results expand the opportunities for adequate description and investigation of real large networks; in particular, they allow calibrating large network models due to their structural characteristics. With the obtained results, one can study and compare different scenarios affecting real large networks.","PeriodicalId":293543,"journal":{"name":"2016 Dynamics of Systems, Mechanisms and Machines (Dynamics)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129213245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the research is the development of the method which allows the calculation time necessary for the analysis of the manipulator mechanism virtual interaction with the external environment to be reduced. With this aim in view the path synthesis of a manipulator mechanism is proposed, using the region assigning permissible configurations in joint coordinate space. The correspondence of output link positions space points and configuration space is investigated. The method of analytical surface assignment is introduced for the manipulator mechanism path calculation. This surface defines a number of configurations, the output link center of them lying in the given straight line segment. The research results have shown that the developed method reduces the calculation time due to virtual modeling of manipulator mechanism motions.","PeriodicalId":293543,"journal":{"name":"2016 Dynamics of Systems, Mechanisms and Machines (Dynamics)","volume":"29 1-2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114027946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We give previously obtained estimates on the number of iterations (cutting planes) of these algorithms. We study one class of the problems with random input data. This paper presents an original method for construction of families of set packing problems, which are polynomially solvable on average.
