Random Majority Opinion Diffusion: Stabilization Time, Absorbing States, and Influential Nodes

no code implementations14 Feb 2023 Ahad N. Zehmakan

Furthermore, we analyze our models for a random initial coloring, where each node is colored blue independently with some probability $p$ and white otherwise.

On the Oracle Complexity of Higher-Order Smooth Non-Convex Finite-Sum Optimization

no code implementations8 Mar 2021 Nicolas Emmenegger, Rasmus Kyng, Ahad N. Zehmakan

We prove lower bounds for higher-order methods in smooth non-convex finite-sum optimization.

no code implementations5 Dec 2020 Ahad N. Zehmakan

We say that an attacker succeeds if a majority of nodes are black at the end of the process.
