Book I · Problem set
Where the chapters meet
A problem here uses two or more chapters at once. That is the whole purpose of the set: a reader who finishes this book should be able to take a cost derived in one chapter and a parameter count from another and answer a question neither chapter asked.

Not yet written. Book I contains load-bearing chapters, so it owes at least 8 cross-chapter problems and 2 that reach back into an earlier book. Those are writable once the chapters they combine are.
