Developed logical methods and algorithms for checking the completeness of a class of k-valued logic functions;
Methods and algorithms for minimizing k-valued logic functions in the class of canonical normal forms have been developed;
A methodology has been developed for constructing optimal correctors of heuristic algorithms based on control materials;
Logical methods and algorithms for creating optimal correctors of heuristic algorithms based on various restrictions and control materials have been created;
Theorems have been proven that the number of single-valued functions of K-valued logic, the minimum number of special classes of K-valued logical functions that correct the choice of incorrect algorithms, that the principle of set invariance does not depend on encoding in the continuation to the end of an indefinite discrete monotonic function;
An algorithmic system for optimal correction of heuristic algorithms has been created to support collegial diagnostics and management decision-making.
