The boxgluepenalty algebra of TeX and its use of \prevdepth
 Frank Mittelbach
 Published paper, TUGboat volume 36, number 1, 2015
 Abstract:
This article discusses certain aspects of TeX’s approach to line breaking and its consequences for automatically calculating the right amount of vertical space between lines in more complex layouts.
It starts with giving a short introduction to the boxgluepenalty algebra used by TeX to model material to typeset. We then look at how the program calculates the vertical glue between lines in which the parameter \prevdepth plays a crucial role. Next we examine different types of output routines and evaluate how and to what extent the TeX algorithms can accommodate their goals.
The final conclusion is that this is an area where we can pose problems that cannot be resolved using current TeX, εTeX, pdfTeX, or XeTeX, unless you restrict the allowable input, as there is no way to obtain some of the information used by TeX’s algorithms for later manipulation of the result.
Like the answer to many questions these days, the situation is (probably) different with LuaTeX — probably, because I haven’t actually tried it, but given the additional possibilities offered by LuaTeX a solution should be feasible.
