Abstract(in English) | We introduce an improved algorithm to locate a segment highway such that the maximum city distance between a given set of n points is minimized (where the city distance is measured with speed v>1 on a highway and 1 in the underlying metric elsewhere avoiding obstacles). We consider that such highway is built in a complex transportation system with H other highways and obstacles. The algorithm runs in O(n^3H^3(log^2n+log H)) time using O(nH) space improving the previous O(n^4H^4) time and space bound. |
