Screen and Tisk directories, useful
for few people, are not contained there; if you would be interested
in them, you would to look directly their source codes (rather then
just to translate and try them).
I will be grateful for information on errors in the programmes. I will even enrich the programmes according to your wishes, with respect to my time possibilities, mood and your insisting on me. But I prefer the programmes being supplemented by you; just blame me for insufficient comments in the source codes. By the way, the first changes in the programme should be your comments on your assumptions on the inquired algorithm, whenever you get an idea, what a given part serves for.
I hope that at least some programmes will prove useful to you, as they have already for my colleagues. I thank them for their development (in an alphabetic order the involved people are David Motl, Rudolf Novák, Leoš Ondra, Tomáš Rezek and Martin Škutek, what is always mentioned in the comments inside the programmes) and for their suggestions.
