Background
“Cognitive Algorithms and Models” and Theory of Algorithms Directions in IIAP, led by Edward Pogossian since 1973 and Hrant Marandjian since 1975, correspondingly, were branched from the Laboratory of Mathematical Logics and Constructive Mathematics led by Igor Zaslavski since 1963 in the noble traditions of the school by Andrey Markov, one of the founders of Computer Sciences along with Turing, Church and Post.
AI studies were initiated at IIAP since its foundation in 1957 by an outstanding mathematician Sergey Mergelyan.
Abstract
1. Cognitive Modeling, or Artificial Intelligence research direction, interpreting Alonzo Church, and then Allan Turing, is a branch of science aimed at understanding humans by providing adequate constructive cognitive models, at least, comparable in effectiveness to
mental doings of humans.
2. Mental doings are a variety of doings collaborative with communities, based on the classification of realities as favourable or damaging, with respect to our utilities, to support our being in the Universe.
3. Cognizing, following the comprehensive psychological models by Jean Piaget are mental doings on learning and organizing mental systems (mss) mostly reducible to a few fundamental rules of revelation and acquisition of mental systems accumulated in communities.
4. We aim to advance in
- refining human ways of cognizing the Universe
- specifying adequate constructive models of cognizing
- revealing constraints on cognizing
- alternating means of cognizing the Universe.
5. At this stage we focus on constructing adequate models of learnable by Piaget cognizers able to advance from certain root cognitive doings to the highest ones.

Dynamical Systems and Networks
Head of Direction Tigran Shahinyan

The dynamical systems and networks, defined by maps or differential equations, are considered. The problems on mathematical modeling of vision and memory mechanism in some of such networks are studied; the pattern formation mechanisms and signal processing are analyzed. The randomness modeling, by means of sequences of pseudorandom numbers, is studied. Some problems on uniform distribution, Markov chains, and independent random sequences, are analyzed; here, some of possible applications are the tests of randomness and evolutionary algorithms. By the machine learning method, some statements on neural activity are considered.
