Augmenting Graphs to Minimize the Diameter
Joachim Gudmundsson (School of IT, Sydney)
We study the problem of augmenting a weighted graph by inserting edges of bounded total cost while minimizing the diameter of the augmented graph. Our main result is a Fixed Parameter Tractable PT 4-approximation algorithm for the problem.
Joint work with Fabrizio Frati, Serge Gaspers and Luke Mathieson.
