 Abstract: The construction of alphabetic prefix codes with unequal letter costs and unequal probabilities is considered. A variant of the noiseless coding theorem is proved giving closely matching lower and upper bounds for the cost of the optimal code. An algorithm is described which constructs a nearly optimal code in linear time.
