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.

Minimum number of real multiplications to multiply two quaternions [closed]
Karatsuba multiplication of two complex numbers can be performed with just three real multiplications (instead of four) as follows:
$$(a+bi)(c+di) = (ac-bd) + i ((a+b)(c+d) - ac-bd)$$
We only need the …
