Dear people, you may be interested in a paper from Reinhold Heckmann and Reinhard Wilhelm called "A Functional Description of TeX's Formula Layout". It is available here [1]; its abstract follows:
While the quality of the results of TeX's mathematical formula layout algorithm is convincing, its original description is hard to understand since it is presented as an imperative program with complex control flow and destructive manipulations of the data structures representing formulae. In this paper, we present a re-implementation of TeX's formula layout algorithm in the functional language SML, thereby providing a more readable description of the algorithm, extracted from the monolithical TeX system.
