About

The mathematical and algorithmic ideas behind RIVET are explained in detail in the paper “Interactive Visualization of 2-D Persistence Modules.” A second paper concerning RIVET’s algorithm for computing the Betti numbers of 2-D persistence modules is in preparation.

RIVET is written in C++, and depends on the qt and Boost libraries.

Contributors:

RIVET was designed by Michael Lesnick and Matthew Wright. Matthew Wright is the primary author of the code, and was the sole author from 2013-2015. Since 2016, Bryn Keller has also played an important role in the development of RIVET, and several others have made valuable contributions to the code as well (some of which will be incorporated into later releases of RIVET):

Here is a list of contributors, with a brief summary of contributions (some of which are still in progress):

  • Madkour Abdel-Rahman (St. Olaf College): Error handling, code distribution
  • Bryn Keller (Intel Labs): Parallel-friendly code organization, command line interactivity, general code hygiene, software design leadership
  • Michael Lesnick (Princeton): Design, testing
  • Phil Nadolny (St. Olaf College): Error Handling, code distribution, code for constructing path through dual graph
  • Matthew Wright (St. Olaf College): Design, primary developer
  • Alex Yu (Princeton)
  • Roy Zhao (Princeton): Handling of multicritical bifiltrations and Rips bifiltrations. Fast vineyard updates.
