\title{Absolute Convergence Check.}
\description{
Compare two values to tell whether an optimization process has converged.
}
\usage{
abs_convergence( p_now, p_prev, epsilon = 1e-6 )
}
\arguments{
\item{p_now}{function value of \emph{i}-th iteration.}
\item{p_prev}{function value of \emph{i-1}-th iteration.}
\item{epsilon}{convergence criterion}
}
\value{TRUE if deemed to have converged, FALSE otherwise}
