\usage{
exhaustiveMP(data, tree=NULL, method="branch.and.bound")
}
\arguments{
	\item{data}{is a \code{\link{phyDat}} (Schliep 2011) object containing DNA or other data.}
	\item{tree}{an optional input tree (used only with \code{method="branch.and.bound"}).}
	\item{method}{an optional string indicatingn method to use: \code{"branch.and.bound"}, implementing a branch-and-bound search (obviously), or \code{"exhaustive"}.}
}
\description{
	This function does exhaustive and branch & bound MP searches.
}
\details{
	Should probably not be used for more than about 8 species (and definitely not more than 10 species).  Performs parsimony calculations using \code{\link{parsimony}} in the \code{phangorn} package (Schliep, 2011).
}
\value{
	A \code{"phylo"} or \code{"multiPhylo"} object that is the MP tree or set of MP trees. It also returns the parsimony scores in \code{attr(trees,"pscore")} or \code{attr(trees[[i]],"pscore")} for the ith tree.
