<title>ABSTRACT</title>
<p>Recent studies have shown that various models can explain
the emergence of complex networks, such as scale-free and
small-world networks. This paper presents a different model
to generate complex networks using a multi-agent approach.
Each node is considered as an agent. Based on voting by
all agents, edges are added repeatedly. We use four different
kinds of centrality measures as a utility functions for agents.
Depending on the centrality measure, the resultant networks
differ considerably: typically, closeness centrality generates
a scale-free network, degree centrality produces a random
graph, betweenness centrality favors a regular graph, and
eigenvector centrality brings a complete subgraph. The importance
of the network structure among agents is widely
noted in the multi-agent research literature. This paper
contributes new insights into the connection between agents'
local behavior and the global property of the network structure.
We describe a detailed analysis on why these structures
emerge, and present a discussion of the possible expansion
and application of the model.</p>
