Informally, an algorithm is a set of explicit instructions used to solve a problem (e.g. Euclid's algorithm for computing the greatest common divisor of two integers). For more specific questions on algorithms, this tag may be used in conjunction with the approximation-algorithms, algorithmic-randomness and algorithmic-topology tags.

[Matrices over Z] - An algorithm for calculating the diagonal with elementary operations
Dear mathoverflow,
Let
$
\left(
\begin{array}{cc}
a & b \newline
c & d
\end{array}
\right)
$
be a matrix with $a, b, c, d \in \mathbb{Z}$, $\gcd(a,b,c,d) = 1$ and $ad - bc = \pm N$, with $N > 0$.
