Program structure analysis in a global optimization
We described the solution of the analysis problem in the BETA multi-language system. The key moment here is joining the analysis algorithms at the isolated stage of the optimization phase. From our point of view, such a stage is necessary in any well-developed optimizing compiler for finding information and control connections and frequency relations between program objects. This stage can be considered as a result of applying to the optimization phase such an universal optimization algorithm as "unloading of repeated parts".
Abstract In this paper, we study a general problem of optimal error reduction in linear multivariable systems. We show how a symptotic regulation can be achieved along with minimization of the H∞ norm of the error transfer function matrix. These resulte are of significance in the development of a new approach to the design of multivariable control systems.
