### 4.3.3 Optimal page breaking

The `ly:optimal-breaking` function is LilyPond’s default method of determining page breaks. It attempts to find a page breaking that minimizes cramping and stretching, both horizontally and vertically. Unlike `ly:page-turn-breaking`, it has no concept of page turns.
