The algorithms of compression of a define area of logical functions represented in maps such as Veich, Carnot surveyed. The analysis of algorithms is spent at compression of a define area on one, two and three variables, that has allowed to reduce dimension of a map accordingly in two, four, eight times. The algorithms are lead up to an engineering technique.
