Projects

Kaggle's 2022 Optimization Competition Vizualization Tool
A vizualization for the 2022 Optimization Challenge hosted by Kaggle. Implemented in vanilla Javascript using p5.js.
Branch-Cut-and-Price algorithm for Parallel Machine Scheduling Problems
The algorithm described in my paper "An Improved Branch-Cut-and-Price algorithm for Parallel Machine Scheduling Problems" listed in the next section. Implemented in C++.
Santa's Stolen Sleight Solution
My solution for a Kaggle's 2016 Discrete Optimization Challenge (link). We placed 11th out of 1127 teams, with a solution 0.18% worst than the 1st place. Implemented in C++.
Santa's Stolen Map - A Solution Visualizer for the Santa's Stolen Sleight Challenge
A visualizer for solutions of the optimization challenge mentioned above. Implemented with PhP and HTML/CSS/Javascript, using the D3.js library for the graphics. Sample solution link.
