On approximating shortest paths in weighted triangular tessellations
Prosenjit Bose, Guillermo Esteban, David Orden +1
We study the quality of weighted shortest paths when a continuous 2-dimensional space is discretized by a weighted triangular tessellation. In order to evaluate how well the tessel…
