Non-Euclidean High-Order Smooth Convex Optimization
Autor: Contreras, Juan Pablo, Guzmán, Cristóbal, Martínez-Rubio, David
We develop algorithms for the optimization of convex objectives that have H\"older continuous $q$-th derivatives with respect to a $p$-norm by using a $q$-th order oracle, for $p, q \geq 1$. We can also optimize other structured functions. We do this

Stochastic Halpern iteration in normed spaces and applications to reinforcement learning
Autor: Bravo, Mario, Contreras, Juan Pablo
We analyze the oracle complexity of the stochastic Halpern iteration with variance reduction, where we aim to approximate fixed-points of nonexpansive and contractive operators in a normed finite-dimensional space. We show that if the underlying stoc

School Bus Routing Problem with Open Offer Policy: incentive pricing strategy for students that opt-out using school bus
Autor: Caceres, Hernan, Duran, Macarena, Lespay, Hernán, Contreras, Juan Pablo, Batta, Rajan
This paper introduces the School Bus Routing Problem with Open Offer Policy (SBRP-OOP) that seeks to improve capacity usage and minimize the bus fleet by openly offering a monetary incentive to students willing to opt out of using a bus. We propose a

Accelerated Bregman Primal-Dual methods applied to Optimal Transport and Wasserstein Barycenter problems
Autor: Chambolle, Antonin, Contreras, Juan Pablo
This paper discusses the efficiency of Hybrid Primal-Dual (HPD) type algorithms to approximate solve discrete Optimal Transport (OT) and Wasserstein Barycenter (WB) problems, with and without entropic regularization. Our first contribution is an anal
