0169-6378I.A. Faradtev and their colleagues had developed a rather efficient tool for the constructive enumeration of combinatorial objects based on the branch and bound method. By means of this tool a number of "sports-like" results were obtained. Some of these results are still unsurpassed.978-90-481-4195-1978-94-017-1972-8Series ISSN 0169-6378ethnology 发表于 2025-3-25 12:11:14
Amorphic Cellular RingsThe enumeration problem for cellular subrings of a given cellular ring has found numerous applications in combinatorics and graph theory (see for example , ). Usually one uses a computer to solve this problem. A general idea underlying searching algorithms for the enumeration of subrings was proposed in and consists of the following.边缘 发表于 2025-3-25 18:59:03
