LoCUS: A multi-robot loss-tolerant algorithm for surveying volcanic plumes
John Erickson, Abhinav Aggarwal, G. Matthew Fricke +1
Measurement of volcanic CO2 flux by a drone swarm poses special challenges. Drones must be able to follow gas concentration gradients while tolerating frequent drone loss. We prese…
On the Minimal Set of Inputs Required for Efficient Neuro-Evolved Foraging
John Erickson, Abhinav Aggarwal, Melanie E. Moses
In this paper, we perform an ablation study of \neatfa, a neuro-evolved foraging algorithm that has recently been shown to forage efficiently under different resource distributions…
A Most Irrational Foraging Algorithm
Abhinav Aggarwal, William F. Vining, Diksha Gupta +2
We present a foraging algorithm, GoldenFA, in which search direction is chosen based on the Golden Ratio. We show both theoretically and empirically that GoldenFA is more efficient…
Multithreaded Filtering Preconditioner for Diffusion Equation on Structured Grid
Abhinav Aggarwal, Shivam Kakkar, Pawan Kumar
A parallel and nested version of a frequency filtering preconditioner is proposed for linear systems corresponding to diffusion equation on a structured grid. The proposed precondi…
Beating the Multiplicative Weights Update Algorithm
Abhinav Aggarwal, José Abel Castellanos Joo, Diksha Gupta
Multiplicative weights update algorithms have been used extensively in designing iterative algorithms for many computational tasks. The core idea is to maintain a distribution over…
