Abstract: Networks govern all aspects of society, including transportation,
communication networks, computer networks, social networks, and networks
for the distribution of goods etc. and the theoretical analysis of such
networks has become a subject of fundamental importance. Networks can be
modelled by graphs.

Such a network (graph) consists of a number of nodes and some connections
(either unidirectional or bidirectional) between nodes. An interesting
measure related to the performance of a network is its diameter which is
the maximum distance between any two nodes of the network. Given a limited
number of connections (degree) available at any node and given the desired
value of the network diameter, the following problem has been of

Degree/diameter problem: Given maximum degree and diameter, what is the
largest possible number of nodes in a network?

In this talk we give an overview of the degree/diameter problem and we
present some recent new results.
