COAgents: Multi-Agent Framework to Learn and Navigate Routing Problems Search Space
Oleksandr Yakovenko, Mahdi Mostajabdaveh, Cheikh Ahmed +4
Although Vehicle Routing Problems (VRP) are essential to many real-world systems, they remain computationally intractable at scale due to their combinatorial complexity. Traditiona…
AIR algebraic multigrid for a space-time hybridizable discontinuous Galerkin discretization of advection(-diffusion)
Abdullah A. Sivas, Ben S. Southworth, Sander Rhebergen
This paper investigates the efficiency, robustness, and scalability of approximate ideal restriction (AIR) algebraic multigrid as a preconditioner in the all-at-once solution of a…
On fixed-point, Krylov, and block preconditioners for nonsymmetric problems
Ben S. Southworth, Abdullah A. Sivas, Sander Rhebergen
The solution of matrices with block structure arises in numerous areas of computational mathematics, such as PDE discretizations based on mixed-finite element methods,…
