Leveraging GNSS and Onboard Visual Data from Consumer Vehicles for Robust Road Network Estimation
Balázs Opra, Betty Le Dem, Jeffrey M. Walls +2
Maps are essential for diverse applications, such as vehicle navigation and autonomous robotics. Both require spatial models for effective route planning and localization. This pap…
Estimating Current-Flow Closeness Centrality with a Multigrid Laplacian Solver
Elisabetta Bergamini, Michael Wegner, Dimitar Lukarski +1
Matrices associated with graphs, such as the Laplacian, lead to numerous interesting graph problems expressed as linear systems. One field where Laplacian linear systems play a rol…
Is Nearly-linear the same in Theory and Practice? A Case Study with a Combinatorial Laplacian Solver
Daniel Hoske, Dimitar Lukarski, Henning Meyerhenke +1
Linear system solving is one of the main workhorses in applied mathematics. Recently, theoretical computer scientists have contributed sophisticated algorithms for solving linear s…
Fast Matlab compatible sparse assembly on multicore computers
Stefan Engblom, Dimitar Lukarski
We develop and implement in this paper a fast sparse assembly algorithm, the fundamental operation which creates a compressed matrix from raw index data. Since it is often a quite…
