Recovering the spatiotemporally dependent diffusion and advection coefficients in a pathway-based Keller--Segel model

We investigate an inverse coefficient problem for an augmented Keller--Segel model arising in the description of phototactic and chemotactic population dynamics. The spatiotemporal evolution of the population density is governed by an advection-diffusion equation in which both the diffusion coefficient and the advectio...

SWAP: A Scalable, Warm-Startable, Anytime Permutation Solver for Optimal Transport

Large-scale and high-dimensional discrete optimal transport often involves a tension between scalability and exact assignment feasibility: many scalable approaches optimize relaxed, factorized, or sparse transport plans rather than maintaining a one-to-one assignment throughout optimization. We introduce SWAP, an itera...
