 cases. We expect the worst KMath benchmarks will perform better than native Python, but worse than optimized

 with doubles. We will measure everything else relative to this one, so time for this test will be `1x` (real time
 on my computer is about 4.5 seconds). The only problem with this approach is that it requires specifying type
 from the beginning. Everyone does so anyway, so it is the recommended approach.

 ## Concrete realizations

 There are 3 approaches to represent polynomials:
-1. For univariate polynomials one can represent and store polynomial as a list of coefficients for each power of the variable. I.e. polynomial  $a_0 + \dots + a_n x^n $ can be represented as a finite sequence $(a_0; \dots; a_n)$. (Compare to sequential definition of polynomials.)
-2. For multivariate polynomials one can represent and store polynomial as a matching (in programming it is called "map" or "dictionary", in math it is called [functional relation](https://en.wikipedia.org/wiki/Binary_relation#Special_types_of_binary_relations)) of each "**term signature**" (that describes what variables and in what powers appear in the term) with corresponding coefficient of the term. But there are 2 possible approaches of term signature representation:
-   1. One can number all the variables, so term signature can be represented as a sequence describing powers of the variables. I.e. signature of term  $c \\; x_0^{d_0} \dots x_n^{d_n} $ (for natural or zero  $d_i $) can be represented as a finite sequence  $(d_0; \dots; d_n)$.
-   2. One can represent variables as objects ("**labels**"), so term signature can be also represented as a matching of each appeared variable with its power in the term. I.e. signature of term  $c \\; x_0^{d_0} \dots x_n^{d_n} $ (for natural non-zero  $d_i $) can be represented as a finite matching  $(x_0 \to d_1; \dots; x_n \to d_n)$.

-All that three approaches are implemented by "list", "numbered", and "labeled" versions of polynomials and polynomial spaces respectively. Whereas all rational functions are represented as fractions with corresponding polynomial numerator and denominator, and rational functions' spaces are implemented in the same way as usual field of rational numbers (or more precisely, as any field of fractions over integral domain) should be implemented.

+and denominator, and rational functions' spaces are implemented in the same way as usual field of rational numbers (or
+more precisely, as any field of fractions over integral domain) should be implemented.

 So here are a bit of details. Let `C` by type of constants. Then:
-1. `ListPolynomial`, `ListPolynomialSpace`, `ListRationalFunction` and `ListRationalFunctionSpace` implement the first scenario. `ListPolynomial` stores polynomial  $a_0 + \dots + a_n x^n $ as a coefficients list `listOf(a_0, ..., a_n)` (of type `List<C>`).

-   They also have variation `ScalableListPolynomialSpace` that replaces former polynomials and implements `ScaleOperations`.
-2. `NumberedPolynomial`, `NumberedPolynomialSpace`, `NumberedRationalFunction` and `NumberedRationalFunctionSpace` implement second scenario. `NumberedPolynomial` stores polynomials as structures of type `Map<List<UInt>, C>`. Signatures are stored as `List<UInt>`. To prevent ambiguity signatures should not end with zeros.
-3. `LabeledPolynomial`, `LabeledPolynomialSpace`, `LabeledRationalFunction` and `LabeledRationalFunctionSpace` implement third scenario using common `Symbol` as variable type. `LabeledPolynomial` stores polynomials as structures of type `Map<Map<Symbol, UInt>, C>`. Signatures are stored as `Map<Symbol, UInt>`. To prevent ambiguity each signature should not map any variable to zero.
