Here are the basics:
Almost all of the simplifier is in simp.lisp. To simplify an
expression like f(a,b), which internally looks like (($f) $a $b),
Maxima calls the function in the operators property of $f, which is
generally called simp-f. This can be fairly simple (for cases like
simp-abs) or very complicated (for simplus (+), simptimes (*), etc.).
You can start by tracing simplifya and then simp-xxx where xxx is a
function that interests you.
Sorry I don't have the time to write more.
