The Global-best Harmony Search (GHS)~\cite{Omran_2008} employs the same modification proposed by IHS with respect to dynamic $PAR$ values. However, it does not employ the concept of bandwidth, being Equation~\ref{e.par} replaced by:  \begin{equation}  \label{e.par_ghs}  x_{m+1,j} = x_{best,j}, x_{best,z},  \end{equation}  where $z\sim U(1,2,\ldots,n)$, and $best$ stands for the index of the best harmony.
