ELM-a fast addition algorithm discovered by a program

A new addition algorithm, ELM, is presented. This algorithm makes use of a tree of simple processors and requires O(log n) time, where n is the number of bits in the augend and addend. The sum itself is computed in one pass through the tree. This algorithm was discovered by a VLSI CAD tool, FACTOR, developed for use in synthesizing CMOS VLSI circuits.<
