Sketch & Project Methods for Linear Feasibility Problems: Greedy Sampling & Momentum
Md Sarowar Morshed, Md. Noor-E-Alam
We develop two greedy sampling rules for the Sketch & Project method for solving linear feasibility problems. The proposed greedy sampling rules generalize the existing max-distanc…
