The existing, intuitive computation models, that is the virtual machines of Turing, Post, Kolmogorov, Schönhage, Aho-Ullman-Hopcroft as well as the algorithms of Markov and Krinitski, and the recursive functions, all lack precise, mathematical formulation. Consequently, an algebra of algorithms is defined using the axiomatic method. The algebra is based on the operations of sequencing, elimination, paralleling and reversing as well as cyclic sequencing, cyclic elimination and cyclic paralleling, all of them performed on the so-called uniterms.
The article is concerned with the analytical evaluation data of the effectiveness of the electrodynamic system reliability control. The basis of the consideration is a study of information efficiency of interaction between a radioelectronic system and that of electronic control. The analytical expressions obtained allow the optimal ratio between the reliable and most effective operating mode of control systems to be chosen. The problem of optimal control of reliability of functioning the radioelectronic control system is stated.
