A generalized utility max-min(UMM) fair algorithm of resource allocation based on piecewise linear function was provided
which supported the upper/lower bounds of resource allocation as well as strictly increasing and continu-ous utility functions.Because of the avoidance of iterative procedure
this algorithm was less complex than water-filling
another UMM fair algorithm.And its simplified version had the same complexity as the narrow-sense UMM fair algo-rithm based on piecewise linear function.This algorithm can be applied in various problems of resource allocation in the field of computer and communication.
