Code that mirrors a paper is the easiest to understand. Verbose, "descriptive" variable names just put more friction between you and the math. You are unlikely to reverse engineer the algorithm from the code unless you were already in a position to understand the terse mathy code to begin with. Just go read the danged paper.
