A Logical Method For Finding Maximum Compatible Subsystems Of Systems Of Boolean Equations, Anvar Kabulov, Erkin Urunbaev, Mansur Berdimurodov Dec 2020

A Logical Method For Finding Maximum Compatible Subsystems Of Systems Of Boolean Equations, Anvar Kabulov, Erkin Urunbaev, Mansur Berdimurodov

Scientific Journal of Samarkand University

The problem of finding the maximum joint subsystem of Boolean equation systems is solved. An algorithm for finding the maximum upper zero of a monotone Boolean function is proposed. An efficient procedure for calculating the values of monotone functions on sets of a - dimensional cube is investigated and developed. An algorithm for solving systems of Boolean equations based on the search for the maximum upper zero of monotone functions of the logic algebra is developed.


An Effective Method For Synthesizing The Abbreviated Disjunctive Normal Form Of A Boolean Function, Erkin Urunbaev Aug 2020

An Effective Method For Synthesizing The Abbreviated Disjunctive Normal Form Of A Boolean Function, Erkin Urunbaev

Scientific Journal of Samarkand University

In discrete mathematics, minimizing Boolean functions in the class of disjunctive normal forms is one of the necessary tasks. This paper presents an effective method for synthesizing the reduced disjunctive normal form of a Boolean function.

Algorithms For Data Reliability Based On A Cryptographic Distributed Database (Blockchain), Fayzullo M. Nazarov, Akmal R. Akhatov, Farkhod F. Meliyev

Scientific Journal of Samarkand University

The ever-growing information flow in modern society, the diversity of information technologies, the complexity of tasks solved on a computer, have set many tasks for users of these technologies. Currently, due to the numerous data streams, the need to process this data in a short period is also growing. Due to the large number of data streams for their storage and processing in the shortest possible time it is required to create automated systems. This research paper presents algorithms for solving the problem of increasing data flow by forming a distributed database. Based on this, methods for optimizing the storage …
