IMHO, not hoohah. That is exactly what I was driving at. The issue, of course, is that "next best" might be in an entirely different context than it was before. For example, a line-breaking strategy might have reported "next best" based on the assumption that it was working in a space 4.5" wide, but because of an issue with a footnote, a higher-level LM has now pushed it to the following page where it is next to a graphic that only leaves it 2.5" to work with. So now the layout needs to be recomputed for that line entirely. So now you have to basically keep track of the options that you have tried, with the scoring opportunities for each one. You basically have to try options until you find one that scores "acceptably" or until there are no others to try, at which point, you take the best one that you have. It seems to me that there are (at least) two approaches: 1. A leaf on the tree says "I am here, put me somewhere on a page", or 2. A higher-level node (page-sequence) says "I have some space here, send me something to fill it." Again, I am ignorant (although I have read the related doc), but reading between the lines makes me think that we are driven to the first option, which I am betting makes dealing with the higher-level layout issues very complicated. I'm also surmising that we probably can't do a good job (or at least can't *know* that we did) until we get the entire page-sequence read anyway, which means that we might be better off reading it in before we start & then taking the second approach. FWIW. Actually, I hope to learn a lot from Keiron's replies.
