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.

Integrality certification for product of two matrices $A B^{-1}$
I considered $x$-adic expansions for $B^{-1}$ and $A$ separately and try to check whether product of terms becomes zero. It is not possible to test integrality of the product $AB^{-1}$ in this way a …

Integrality certification for product of two matrices $A B^{-1}$
Let's consider two non-singular integer matrices $A,B \in\mathbb{Z}^{n\times n}$. I want a test to check if $A\times B^{-1}$ is integral (or no denominators). I am referring the unimodular certificati …
