Writing out long variable names while working on a mathematical model is like writing the same text with ten times the number of characters. It's neither elegant nor efficient.

Imagine you're playing around with variables and model configurations in complex mathematical terms, but one formula stretches over two pages and you always need to cross out and rewrite whole words.

we're not taking about homework but published paper.

i don't publish code at conferences with

   var x, j, i, ii, iii, i2, h, ji...

even though i find it pretty convenient when writing prototypes.

math people are just sloppy :)
