Mathematical Modeling in the Textile Industry
Krasimir Yordzhev, Hristina Kostadinova
A mathematical model, describing some different weaving structures, is made in this article. The terms self-mirror and rotation-stable weaving structure are initiated here. There a…
On A. V. Anisimov's problem for finding a polynomial algorithm checking inclusion of context-free languages in group languages
Krasimir Yordzhev
The work investigates the problem of whether a context-free language is a subset of a group language. A.~V. Anisimov has shown that the problem of determining the unambiguity of fi…
On some randomized algorithms and their evaluation
Krasimir Yordzhev
