A HEURISTIC SEARCH FOR THE BEST HIERARCHICAL STRUCTURE

J. STEFAŃSKI

Systems with hierarchical structures consisting of controlled elements are considered. The elements are described by exponential functions. The objective function is the sum of…

THE IMPOSSIBILITY OF GENUINELY SELF‐STEERING MACHINES: A FUNDAMENTAL THEOREM ON ACTOR‐SYSTEMS

A. AULIN‐AHMAVAARA

It is proved that the separation of internal state from external input, characteristic of automata, machines and machine‐like systems, is impossible in genuinely self‐steering…
