\title{Compute bandwidth for an undirected graph}
\description{Compute bandwidth for an undirected graph}

\usage{
bandwidth(g)
}

\arguments{
  \item{g}{an instance of the \code{graph} class with \code{edgemode}
    \dQuote{undirected}}
}

\details{
The bandwidth of an undirected graph G=(V, E) is the maximum distance between 
two adjacent vertices. 
See documentation on bandwidth in Boost Graph Library for more details.
}

\value{
\item{bandwidth}{the bandwidth of the given graph}
}
