Abstract: Recovery of a dynamic system from its functioning is a problem of current interest in the theory of control systems. As a behavior model of gene network regulatory circuit, a discrete dynamic system has been proposed, where coordinates correspond to the concentration of substances, while special functions, which depend on the system value in the previous moment, account for their increase or decrease. Pseudo-polynomial discrete dynamic system recovery algorithms with additive and multiplicative functions have been obtained earlier. The generalized case of arbitrary threshold functions is considered in this article. Algorithms for significant variables recovery and threshold functions weight regulation, having pseudo-polynomial testing complexity, are given. These algorithms allow one either to recover the system completely, or to lower the threshold function dimension.

Keywords: discrete dynamic system; genetic network; threshold function; testing; recovery problem.
