In the Optimum Communication Spanning Tree (OCST) problem, a spanning tree for a complete graph has to be found that satisfies the communication requirements needed by the vertices with a minimum total cost. A special case of the OCST problem is the Optimum Distance Spanning Tree (ODST) problem, where the requirements are restricted to be constant. Both problems are known to be NP-hard. In this book, a randomized algorithm has been proposed to efficiently solve two special cases of the ODST problem. This can be achieved by randomly generating spanning trees with certain properties.

Produktbeschreibung
In the Optimum Communication Spanning Tree (OCST)
problem, a spanning tree for a complete graph has to
be found that satisfies the communication
requirements needed by the vertices with a minimum
total cost. A special case of the OCST problem is
the Optimum Distance Spanning Tree (ODST) problem,
where the requirements are restricted to be
constant. Both problems are known to be NP-hard. In
this book, a randomized algorithm has been proposed
to efficiently solve two special cases of the ODST
problem. This can be achieved by randomly generating
spanning trees with certain properties. This book
also includes the history of the OCST problem along
with a literature survey. This is in addition to a
discussion on the different deterministic algorithms
that exist for enumerating all spanning trees of a
graph. An empirical study has been conducted that
showed that the proposed algorithm can yield near-
optimum solutions. The experiments involve testing
the proposed algorithm to solve these special cases
using several randomly generated graphs, in addition
to the hypercube and butterfly network topologies to
some specified dimension.
