comment Replacing composite variables by a single variable
Thanks for your post Andrzej. Do you recommend using PolynomialReduce for general replacements? I noticed that using Simplify is computationally demanding (compared to replace /.) even for very simple substitutions.

comment Replacing composite variables by a single variable
Thanks, I figured it out about the same time as you and RM. Sorry to edit. I'm hoping to find a general way to make a substitution that does not require analysis of the FullForm and construction of an elaborate replacement syntax.

comment ordering of functional eigenvalues
@murray: VitaliyKaurov added the Log[...] example to his answer in response to my suggestion, subsequent to my comment about the trigonometric expression being essentially numeric.

comment ordering of functional eigenvalues
@murray. You need to follow the edit history of the conversation. The example I referred to in the comment addressed to VitaliyKaurov was the trigonometric one (1/2 (Sin[1] + Sqrt[5 + 12 Cos[2] + 6 Cos[4] + 4 Cos[6] + 4 Cos[8] + 2 Cos[12]] Sin[3] + Sin[5] + Sin[9])), which is most certainly numeric. The Log[...] example was one I proposed myself, and is of course non-numeric, as I pointed out in my comment addressed to you yesterday.
