Questions tagged [programming]
For mathematical questions related to programming, and questions where a computer-aided solution is strongly suggested. A strong connection with a mathematical topic is needed to make programming questions on-topic. This should not be the only tag. Consider also using the tags (algorithms), (numerical-methods), or (linear-programming).

Modular square root function with Hensel's Stronger Lemma; algorithm for $\bmod 2^x$? Also $x^2 = a\pmod{p^n}$ when $\gcd(a,p) \neq $1
I'm programming a solution to HackerRank's Project Euler 100, which is a much stronger variant than the original question, so I have to essentially make a quadratic solver, which involves a lot of ...

Is there an algorithm for finding every isolated singular point on an algebraic variety, or a programming language that implements this?
Suppose one wishes to test if a given algebraic surface f(x,y,z,w) = 0 in projective 3 space has singular points, that is df/dx = df/dy = df/dz = 0, and one also wishes to calculate these singular ...

Does the set of all programs form a group that acts on machine state (essentially, i.e. with a few exceptions)?
Since the only thing a computer can do is modify its machine state, and you can always change from one state into another state (there exists such a program) and so each program is invertible; and if ...
