Enumerator printing out strings from a language Write down the algorithm of an enumerator that prints out EXACTLY ONCE every string in the language L = {7m+ 2 | m ∈ N} over the alphabet A = {0, 1, 2, 3, 4, 5, 6, 7, 8...
So, the algorithm asks you to list out every number of the form $L = \\{7m + 2 ~\vert~ m \in \mathbb N\\}$. Note that since we should just print each number once, let's check if by iterating over the different values of $m$, if we can get the same number. \begin{align*} 7a + 2 = 7b + 2 \\\ 7 (a - b)...

Enumerator polynomial
In coding theory, the weight enumerator polynomial of a binary linear code specifies the number of words of each possible Hamming weight. The distance enumerator polynomial is
and when C is linear this is equal to the weight enumerator.

generating function as english statement An ordinary enumerator is given as $(1+x+x^2)^p$. This is being understood as follows: > There are 2 each of p kinds of objects.The ordinary enumerator for selecting none (...
The ordinary enumerator for selecting none or five or all nine of the objects of that kind is $(1+x^5+x^9)^{100}$.

Find B(x) such that $A(x) = P(x) \cdot B(x) $ > A(x) is enumerator (generating function) of partitions of number such that contain exactly $1$ (but maybe multi times) of $2,3,5$. P(x) is enumerator of all partitions. ...
The enumerator of all partitions of number is $$ P(x)=\sum_n P_{n}x^{n} = (1+x+x^2+\ldots)(1+x^2+x^4+\ldots)(1+x^3+x^6+\ldots)\cdot\ldots\cdot(1+x^{k}+ So in similar way we can create the second enumerator which has a form defined by the constraints given in your task $$ A(x)=\leftx^2(1+x^2+x^4+\ldots)

why does multiplying a fraction e.g. enumerator/divisor with divisor/enumerator give 1? I just found out that if you want to get 1 with the fraction: $$\frac{5}{2}$$ Then you multiply it with: $$ \frac{2}{5} $$ Does a...
This is called The Inverse Property of Multiplication. Take $x$, then $$x \cdot \frac 1 x = 1$$ In your case of $x=\frac 5 2$, $$ \frac 5 2 \cdot \frac{1}{\frac 5 2} = \frac 5 2 \cdot \frac 2 5 = 1 $$

Double vertical bars I've been reading the Wikipedia article on CSP (< and one of the first formulas there has double vertical bars in it. $$ {{w}}={\arg \max }_{{\mathbf {w}}}{\frac {\left\|{\mathbf {wX}}_{1}\right\|...
The norm of a matrix $A$ can be defined similarly to the norm of a vector. In your case, this $\Vert A\Vert$ means $\left(\sum_{i,j} a_{i,j}^2\right)^{1/2}$, known as the _Frobenius norm_. However, since $\vec w$ is likely a row-vector, the product $\vec wX$ is itself a row-vector. Thus the norm $\V...

Plain integer partitions of $n$ using $r$ parts Division of number $n$ on parts $a_1,...,a_r$ where $a_1 \le ... \le a_r$ we call a plain if $a_1 = 1$ and $a_i - a_{i-1} \le 1$ for $2 \le i \le r$. Find enumerator (ge...
The set of plain division of $n$ into $r$ parts is in bijection with the set of divisions of $n$ into distinct parts _whose largest part is equal to $r$_. The bijection is conjugation, i.e. reflecting the Ferrer's diagram. Since there must be a part of size $r$, the factor must be $x^r$ instead of $...
