Refactoring Recursion

Recursion is the fundamental looping mechanism in functional programming. This talk shows patterns of recursion using Haskell. It shows those patterns for list structure only. This makes it easier for beginners to understand recursion schemes by focusing on their operation with lists. We start by writing explicit recursive versions of sum, product, and length of lists, then factor them into fold functions. We proceed in a similar manner with other folds, unfolds, and refolds with many examples of the patterns in operation. We end by mentioning factoring recursion out of data.

About Harold:

Harold Carr does blockchain research at Oracle Labs (using Haskell). At Oracle and Sun, he worked on cloud infrastructure, InfiniBand transport, and remoting system technology (i.e., REST, SOAP, CORBA, and RMI). He has worked on distributed Lisp and distributed C++ with Hewlett-Packard Research Laboratories, was Chief Architect of Lisp technology at Autodesk, and was a logic simulation consultant for Cirrus Logic. He holds a Ph.D. in Computer Science from the University of Utah.
