  • Abstract
    A new algorithm is presented for constructing nearly optimal prefix codes in the case of unequal letter costs and unequal probabilities. A bound on the maximal deviation from the optimum is derived and numerical examples are given. The algorithm has running time O(t \\cdot n) , where t is the number of letters and n is the number of probabilities.
