What is recorded here?
Knuth and Plass represented paragraph material with boxes, glue and penalties and selected line breaks through a global optimization procedure using dynamic programming. Choosing each line greedily can damage later lines. A paragraph-wide objective allows spacing and break penalties to be balanced across the paragraph. This is a specific algorithmic contribution, separate from the WEB programming method.
