See the instructions for getting the preprint below. 15, No. 1, February 1993, pp. Large presentations arise in practice which are poorly suited for either human or computer use. Presentation simplification processes which take bad presentations and produce good presentations have been developed. Substantial use is made of substring searching and appropriate techniques for this context are described.
Effective use is made of signatures and change flags.
Change flags are shown to be the most beneficial of the methods tested here, with very significant performance improvement. Experimental performance figures are given. Then uncompress and handle however you process a dvi file. Some useful hints. A new window will pop up in which you will be asked to type in the name under which you want to save the file.
