Abstract
This poster describes a new algorithm called B# which is needed to find the visibility graph of a
polygonal region with obstacles defined by simple polygons. It focuses on finding the entire
visibility graph among polygonal obstacles which has been tuned in a variety of test cases. The
obstacles are restricted to simple cases, i.e. where no edge intersects any other edges. The visibility
graph problem itself has long been studied and has been applied to a variety of areas. A common
use for it has been for finding the shortest path. The B# algorithm has been implemented
adjustments made and experimental comparisons via time measurements carried out. A
comparison between “Naïve algorithm” and “Naive algorithm with B#” was performed with
different numbers of vertices. The B# algorithm by itself doesn’t calculate the visibility graph. It
selects the
next best obstacle
where the calculation should proceed.
