- title: Linear-time breadth-first tree algorithms
- -- an exercise in the arithmetic of folds and zips
-
- abstract: This is a paper about an application of the mathematics
- of zip, fold (reduce) and accumulate (scan) operations on
- lists. It gives an account of the derivation of a linear-
- time breadth-first enumeration function, and of a subtle
- and efficient breadth-first tree labelling function.
