I actually used the descriptions of the Herrmann and Kaiser algorithms
quoted in Ichige's paper because I didn't have immediate access to
those papers. I just placed a request for my university's offsite
copies of the relevant journals; barring complications, I can send you
copies of the articles when I receive them in a few days.
