complexity of the computer hardware and software (abstract only)
The complexity characteristics of informal algorithm models, formal algorithm systems and of an algorithm device have been examined. Methods of efficient informal algorithm constructions have been systematized. The parameters of time and instrumental complexities of hardware/software environment have been precised. Introduce information characteristics as programm and structure complexities. Describe optimization methods of the four complexity charadteristics for each hierarchical level of computer environment presentation. Optimization first of all assumes using of not contradictional methods of time and programm minimization considering about relative value of each characteristic. Taking into account relative price value of each parameter, optimization first of all assumes using of not contradictional methods of minimization of time and program complexities by means of some increasing of instrumental and structural complexities, but keeping computer's functional abilities. Expedience of using complexity parameters has been demonstrated by microprocessors evolution analysis.
