Tree Transformation in APL with Arrays and Inverted Tables
Dyalog User Meetings · Talk · YouTube title: High-performance Tree Wrangling, the APL Way // Aaron Hsu // Dyalog '18
Why it's here
HN recommends it as a striking example of high-performance tree handling with array programming.
What it covers
Aaron Hsu shows how to manipulate and transform tree data in APL using arrays and inverted tables instead of pointers. He claims much smaller code, better performance and easier parallelisation.
