Hi,

I’m pleased to announce I’ve had a paper accepted for presentation at The 34th Symposium on Implementation and Application of Functional Languages (https://ifl22.github.io https://ifl22.github.io/). The paper is entitled: How to fold and color a map: Comparing Use-Cases of Tree-Fold vs Fold-Left. You may view the article here https://drive.google.com/file/d/1-65beERt9UylSmxgsWe-gcl3Hz8JvjzC/view?usp=s... as it is not yet available on /lrde/doc, pending an IT issue.

ABSTRACT

In this article we examine some consequences of computation order of two different conceptual implementations of the fold function. We explore a set of performance- and accuracy-based experiments on two implementations of this function. In particular, we contrast the traditional fold-left implementation with another approach we refer to as tree-fold. It is often implicitly supposed that the binary operation in question has constant complexity. We explore several application areas which diverge from that assumption: rational arithmetic, floating-point arithmetic, and Binary Decisions Diagram construction. These are binary operations which degrade in performance as the fold iteration progresses. We show that these types of binary operations are good candidates for tree-fold.

Kind regards Jim
