\title{ Extract wholes in the smaller incidence matrix}
\description{
 Extract wholes in the smaller incidence matrix, which might be active in the optimal solution with respect to the bigger incidence matrix in the sequential approach introduced in the reference.
}

\usage{
optimalRM(xxbig, xx1, xx2)
}

\arguments{
  \item{xxbig}{The bigger incidence matrix in the sequential approach.}
  \item{xx1}{The smaller incidence matrix in the sequential approach.}
  \item{xx2}{The difference incidence matrix between xxbig and xx1.}

}

\details{
In the sequential approach, we need to extract some other wholes in the smaller incidence matrix besides the active ones, which are already identified by the ILP calculation. See reference for details. This function will be invoked in \code{sequentialRM}.
}

\value{
Return a logical vector with the length of the number of columns of xx1.
