Rectilinear Steiner Tree
The minimum rectilinear Steiner tree problem (MRST) is a variant of the geometric Steiner tree problem in the plane, in which the Euclidean distance is replaced with the rectilinear distance. The problem arises in the physical design of electronic design automation. In VLSI circuits, wire routing is carried out by wires running only in vertical and horizontal directions, due to high computational complexity of the task.

Famous quotes containing the words steiner and/or tree:
“The violent illiteracies of the graffiti, the clenched silence of the adolescent, the nonsense cries from the stage-happening, are resolutely strategic. The insurgent and the freak-out have broken off discourse with a cultural system which they despise as a cruel, antiquated fraud. They will not bandy words with it. Accept, even momentarily, the conventions of literate linguistic exchange, and you are caught in the net of the old values, of the grammars that can condescend or enslave.”
—George Steiner (b. 1929)
“Strong to break dead things,
the young tree, drained of sap,
the old tree, ready to drop,
to lift from the rotting bed
of leaves, the old
crumbling pine tree stock.”
—Hilda Doolittle (1886–1961)
