In many applied scientific problems, diversity of the results set is no less important than their amount. An example of such problem is the virtual drug screening. According to the principles of drug development, the structural diversity is one of the key characteristics of the resulting molecules set. At the same time, virtual drug screening is a time- and resource-consuming computational...

One of important classes of combinatorial and discrete optimization problems [1] is formed by enumeration problems. During their decision one needs to determine a number of objects with specified properties. The simplest examples of such problems are well known problems about chess rooks, chess queens, etc. For some of them precise analytic decisions are known, while to solve others one needs...

One of promising approaches to the logic control systems (LCS) design is their implementation within logic multicontrollers (LMC) basis which are presented as the collective of similar controllers connected by network with regular topology [1]. One of the problems corresponding to a class of discrete combinatorial optimization problems [2] that arise during LMC design is a problem of getting...

There is a well known extensive class of optimization problems where parameters are discrete variables. They include problems from graphs theory, scheduling, operations research and so on. One part of them named as hard solved problems and forming a NP complexity class can’t be solved precisely for reasonable computing time therefore in practice for their solving heuristic methods are used. At...

Usually if the cryptanalysis is considered as a SAT problem then it is called a SAT-based cryptanalysis. In this case to find a secret key it is sufficient to find a solution of corresponding satisfiable SAT instance. Here we consider the SAT-based cryptanalysis of the Bivium keystream generator. This generator uses two shift registers of a special kind. The first register contains 93 cells...

In every volunteer computing project some deadline is used. It is the time limit for execution of a computational tasks on a user computer. If a task wasn’t processed in deadline, then project server sends this task to another user’s host.
The value of deadline has a great influence to effectiveness of a volunteer computing project. If this value is low, then a lot of hosts will not keep...

В исследовании показано, что виртуальное сообщество российских участников добровольных распределённых вычислений (volunteer computing, VC) на платформе BOINC может быть рассмотрено в форме сети. В качестве узлов сети рассмотрены 2 типа объектов: участники сообщества (аккаунты пользователей, зарегистрированных на сайте boinc.ru) и исследовательские проекты, в которых пользователи принимают...
