> But actually treating poem as an algebra problem really is taking it too far.

Not really, a lot of poems (the symbolists come to mind) are actually meant to be treated as semantic puzzles or mathematical problems. Lewis Carroll is perhaps the most famous - and one of the greatest example of the intersection of maths, logic and poetry.

One of the best poetical analysis I had the pleasure of reading in recent years is a very probabilistic (rather than algebraic) reading of the French poet Mallarme, who was himself fascinated by randomness and probabilities:

Highly recommended read.
