Incremental λ-Calculus

The goal of the Incremental λ-Calculus project is to extend database technology for low-overhead incremental computation, based on finite differencing, and apply it to higher-order languages.

ILC: Creating an API for producing changes

In incremental lambda calculus, to update the output we need a description (represented as data) of how the input of a program changes. Comparing the old and the new input is overly expensive; instead, it would be convenient to create a description of the changes while they happen. The goal of this thesis is to design (and implement) a solution to this problem, focusing on the case of collections.
