Abstract

Given a general arithmetic expression, we find a computation binary tree representation in O(log n) time using n/log n processors on a concurrent-read, exclusive-write, parallel random-access machine.A new algorithm is introduced for this purpose. Unlike previous serial and parallel solutions, it is not based on using a stack.
