Two-Level Grids for Ray Tracing on GPUs
We investigate the use of two-level nested grids as acceleration structure for ray tracing of dynamic scenes. We propose a massively parallel, sort-based construction algorithm an...

A hybrid shifting bottleneck-tabu search heuristic for the job shop total weighted tardiness problem
: In this paper, we study the job shop scheduling problem with the objective of minimizing the total weighted tardiness. We propose a hybrid shifting bottleneck - tabu search (SB-T...
