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 task ... More

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 to p ...

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 t ... More

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 and th ... More

Consider an opportunity to create different topologies and test software behaviour without the need to construct real network topologies with real nodes. One of such examples is an application running on multiple nodes over a network. We cannot rely o ... More

Docker is a one of the most popular systems for container virtualization on the market. It gives user a lot of possibilities, but its use requires root access which is sometimes dangerous. We propose a set of simple command line tools for managing Docker containers called YASTD (Yet Another Simple Tools for Docker). It has three purposes: - to allow users to create containers remotely access ... More
