WebResults: In this paper, we present the wavefront alignment algorithm (WFA), an exact gap-affine algorithm that takes advantage of homologous regions between the sequences to accelerate the alignment process. As opposed to traditional dynamic programming algorithms that run in quadratic time, the WFA runs in time

A SIMD unit can have up to 10 wavefronts in flight at once. Each wavefront contains 64 threads. Hence a SIMD unit can have up to 640 threads in flight at once (in multiples of 64). cindy collegeWebterrain with a known cost map is a dynamic-programming "wavefront propagation" Terrain is modelled by a uniform "grid" or tessellation of cells of uniform size and shape. Each cell has an associated cost which represents an average cost-per-unit-traversal-distance for the terrain within the cell. The algorithm works by expanding a .
