Schema illustrating the structure of a graph constituting the environment of the agents'
activity
•
The relationships between the agents and the environment and, when necessary,
mutual relationships between the agents.
Briefly speaking, in order to create a project of the agent system it is necessary
to specify the structure of the system, i.e. the environment and the agents and the
relationship between them.
The environment is defined as follows (Fig.
4.1
):
•
The environment has the form of a graph consisting of nodes (
T
—a set of nodes)
and edges (
B
—a set of edges). The edges are connected with the nodes—direct
connections (neighbouring nodes). What is more, connections can be made with
all nodes (bus), which enables two optionally chosen nodes to send resources as
well as pieces of information directly between themselves, however, it is accepted
that the efficiency of such transfer is lower than sending through the connections
between the neighbouring nodes.
Through these connections the agents may also relocate in the environment.
•
The resource we consider exists in the nodes of the environment. The quantity of
this resource in the node
t
(
t
∈
T
) is denoted by the real number
r
t
.
