Full references for the methods shown here appear in the references section of the paper

Note: some of the results by Shan et. al. [2008] where obtained using the program available on their web site.
As this program has a few parameters, the results may vary. We did our best to present the optimal results,
but we acknowledge the possibility that better results may be obtained with other parameter values
