Depends on who the paper is for. Theoretical CS papers for example, often don't have any code, but sometimes have pseudocode (for example in page 4 of PRIMES is in P [0]), to describe their algorithms. If the paper is written for people with less math background then writing up the algorithm in at least once language as a sample implementation is the way to go. Also there's nothing wrong with doing both? [0]: https://annals.math.princeton.edu/wp-content/uploads/annals-v160-n2-p12.pdf https://annals.math.princeton.edu/wp-content/uploads/annals-...
