Abstract

In this article, a model of binary programs that implement the logic algebra functions (Boolean functions) is considered. These programs consist of one or several modules, which include the following three types of commands: computational, branching, and procedure call commands. The model under study also allows recursive procedure calls. It means that the procedures can call themselves, either directly or through other procedures, during the program execution. The concept of an arbitrary basis for branching commands is introduced as a generalization of the known models. The methods for calculating the lower and upper bounds of the Shannon function for the complexity of Boolean functions implementation in the class of binary programs are presented. The complexity of a binary program is understood as the integral weight of all commands of its subprograms. The methods allow establishing the Shannon function asymptotic bounds in the case when the specific weight of branching commands is less than the specific weight of computational commands. The obtained results contribute substantially to further development of the theory of synthesis and complexity of discrete control systems.

Keywords: binary programs, Shannon function, asymptotic bounds
