Industry:Computer science
The distance between two points measured along axes at right angles. In a plane with p<sub>1</sub> at (x<sub>1</sub>, y<sub>1</sub>) and p<sub>2</sub> at (x<sub>2</sub>, y<sub>2</sub>), it is
Industry:Computer science
The distance from the beginning of a string to the end of a segment in that string.
Industry:Computer science
The distinguished initial or fundamental item of a tree. The only item which has no parent.
Industry:Computer science
The dominant style of parallel programming, where all processors use the same program, though each has its own data.
Industry:Computer science
The dual of a planar graph, G, is a graph with a vertex for each region in G and an edge between vertices for each pair of adjacent regions. The new edge crosses the edge in G which is the boundary between the adjacent regions.
Industry:Computer science
The end characters of a string. More formally a string v is a suffix of a string u if u=u'v for some string u'.
Industry:Computer science
The expected running time of the best possible deterministic algorithm over the worst possible probability distribution on the inputs.
Industry:Computer science
The expected running time of the best possible randomized algorithm over the worst input.
Industry:Computer science
