The unbounded version of the 1D range assignment problem for radio-stations is studied. Here a set of n radio stations are placed arbitrarily on a line. The objective is to assign ranges to these radio-stations such that the total power consumption is minimum. A simple incremental algorithm is proposed which produces optimum solution in O(n 3) time and O(n 2) space. This improves the running time of the best known existing algorithm by a factor of n.
