VISUALIZING SYSTEMS

R.J. DRYDEN

A method is described by which systems may be represented as a collection of interlocking shells which indicate the boundaries of the components. It is suggested that this method…

ADAPTIVE PROBLEM‐SOLVING SYSTEMS

V.P. GLADUN, N.D. VASCHENKO

Three types of adaptation are distinguished in problem‐solving systems: Adaptation to the environment, adaptation to the problem and adaptation to the class of problems. An…

ON THE LOGIC OF DISCRETE SYSTEMS DYNAMICS

C.V. NEGOITA, R. ROMAN

This paper deals with the area of problems concerning the discrete systems dynamics and is also related to Wonham's principle of internal model. The authors consider the case of…

FIXED BLOTS IN TOLERANCE AUTOMATA

M.W. WARNER

We prove that every input chain of a finite l‐tolerance automaton with inertia whose state space has a non‐zero Euler characteristic has a fixed blot, i.e. maps to itself a set �…

MATHEMATICAL METHODS AS COGNITIVE PROBLEM‐SOLVERS

M.K. CHYTIL

The applications of mathematics to the solving of factual problems should run in a certain prescribed form called a mathematical method. Whereas a mathematical method is an only…

DEFINING STRUCTURAL DESCRIPTIONS

M.A. BAUER

A formalism for representing descriptions based upon labelled directed graphs is presented. Node and edge labels are assumed to lie in lattice‐like structures which capture…

THE NEURAL BASIS OF EEG WAVES

P.P. NELSON

Using results explained in previous papers, we show how specific properties of great cortical cells give rise to electro‐encephalographic events. Analogies between EEG rhythms and…

MODELLING CONTROLLERS USING FUZZY RELATIONS

J.F. BALDWIN, N.C.F. GUILD

An established method of modelling a controller using a fuzzy relation is examined in the light of recent criticisms. An alternative formulation of the fuzzy relation is described…
