Abstract
The paper considers the problem of distributed
adaptation of the functional integration structure of a
multi-agent system in a dual-tasking environment from the
point of view of organizing multi-agent search and use of
the functional emergence effect provided by different
structures of functional integration. The considered
problem belongs to a wider class of problems of structural
adaptation and self-organization. Models of functional
integration, in particular, models based on general
quantitative characteristics of the functional roles
distribution of agents and models based on local qualitative
characteristics of the functional roles distribution of agents,
taking into account the specifics of functional links
established between agents have been considered in the
paper. The problems of the distributed adaptation of the
functional integration structure have been analyzed,
including the problem of the functional specialization of
agents in a multitasking environment. Various ways of
organizing structural changes have been considered,
including multi-agent parametric adaptation based on a
local structural parameter. Multi-agent structural
adaptation based on reinforcement learning methods, in
particular, multi-agent structural adaptation based on the
normalized exponential function method (MSA-softmax)
and multi-agent structural adaptation based on the upper
confidence bound method (MSA-UCB) has been proposed.
The distributed adaptation methods simulation results have
been presented, which showed the advantage of multi-agent
structural adaptation over multi-agent parametric adaptation.
