This study investigates combinatorial substitution schemes with various constraints on cycle sizes: lower bounds, upper bounds, and two-sided bounds. For the proposed schemes, we solve several enumerative combinatorics problems: determining the number of possible outcomes, constructing direct numbered enumerations, solving numbering problems (establishing bijective correspondences between indices and types of outcomes), deriving probability distributions over ...

The article studies the schemes of particle allocation to cells in indistinguishable (scheme A) and distinguishable (scheme B) groups with the outcomes of achieveming a given minimum cell filling level. The schemes are analyzed by the enumerative method based on the construction of an iterative random process of direct non-repetitive numbered enumeration of their outcomes ...

We consider a scheme C of allocating r = r(k) indistinguishable particles to n distinguishable cells until the occurrence of the event Ak, when for the first time there are k (k r) non-empty cells. The pre-asymptotic analysis of the scheme is carried out by an original enumerative method (EM) along the following lines: nonrepetitive ...

A given range of fixed elements of a permutation means a certain number of elements between the elements located at the extremes in the permutation in each sequence. The proposed scheme is analyzed in the pre-asymptotic region of feasible parameter values using the enumerative method designed by the author, i. e., the enumerative combinatorics problems ...

The probabilistic distributions of maximum cell occupancylevels (problem 2) and the numbers of outcomes given their fixed values are studied in models of equiprobable outcomes of the schemes for placing R particles in n cells. The schemes differ in all possible pairwise qualities of cells and particles in terms of their distinguishability. A method for ...

In the paper, we consider the ways to improve the quality and economic efficiency of development and production of complex innovative electronic devices, among which are laser gyros (LGs). Development, manufacturing and testing of high-tech LG are relatively expensive. The accurate thermal modeling at the early stages of LG designing is an effec- tive way ...

The article deals with a permutation scheme of size n with r successive series of
increasing elements. I solve the problems of finding the number of outcomes of the
scheme, and design the procedure for their enumeration using r successive schemes
of combinations of an array of different compositions of series of increasing serial
numbers of permutation elements. The ...

An enumerative method is proposed for the analysis of combinatorial schemes in the
pre-asymptotic region of variation of their parameters based on the construction of their
probabilistic mathematical model, which represents for each scheme an iterative
random process of sequential non-repeated formation of all its outcomes with a certain
discipline of their numbering by unitary addition of certain elements ...

The problems of the scheme analysis here consist in arranging the procedure
for enumerating the outcomes of the scheme, determining their number, solving
the problem of numbering these outcomes, and their modelling using the results
obtained here through similar studies of the same scheme but without restrictions.

In the subasymptotic range of variation of parameters of combinatorial schemes, we consider a method of analysis based on explicit enumeration of their outputs in the following directions: enumeration of the output enumeration graph, determination of their number, solution of the numeration problems for outputs in the direct and inverse settings, evaluation of their probability distribution, and construction ...
