Combinatorial research has proceeded vigorously in Russia over the last
few decades, based on both translated Western sources and original
Russian material. The present volume extends the extremal approach to
the solution of a large class of problems, including some that were
hitherto regarded as exclusively algorithmic, and broadens the choice of
theoretical bases for modelling real phenomena in order to solve
practical problems.
Audience: Graduate students of mathematics and engineering interested
in the thematics of extremal problems and in the field of combinatorics
in general. Can be used both as a textbook and as a reference
handbook.
