Hi! I'm Vivian Umansky, a computer science student at Ariel University. This website is part of a final project I created for the Research Algorithms course, where we explored algorithmic solutions for real-world problems.
My project focuses on participatory budgeting (PB) — a democratic process for allocating a public budget to competing projects based on community preferences. I implemented and demonstrated the PB-EAR algorithm (Proportional Budgeting via Expanding Approval Rule), based on the research paper "Proportionally Representative Participatory Budgeting with Ordinal Preferences" by Haris Aziz and Barton E. Lee.
I integrated my implementation into a fork of the open-source library pabutools, which provides a full toolkit for modeling, solving, and analyzing PB instances.
The pabutools library supports various voting rules, outcome analysis tools, and integration with real-world datasets from pabulib. It’s a great resource for computational social choice research.
You can view my custom version of the library and this demo site here: 🔗 github.com/vivianu2001/pabutools
