Iceland is sometimes thought to be a part of Scandinavia.
In computational geometry , a sweep line algorithm or plane sweep algorithm is an algorithmic paradigm that uses a conceptual sweep line or sweep surface to solve various problems in Euclidean space .. computational geometry. computational geometry. algorithmic paradigm. algorithmic paradigm. Euclidean space. Euclidean space. It is one of the key techniques in computational geometry .. computational geometry. computational geometry. The idea behind algorithms of this type is to imagine that a line -LRB- often a vertical line -RRB- is swept or moved across the plane , stopping at some points .. Geometric operations are restricted to geometric objects that either intersect or are in the immediate vicinity of the sweep line whenever it stops , and the complete solution is available once the line has passed over all objects .
