Facing algorithm ... programming interviews. I interview a lot of candidates. Many of them can answer Big O notations of many data structures, in a blink of an eye, while they fail to describe ...

Abstract: 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 ...

While most of the existing methods solve such operations via linear programming, the approach proposed in this paper relies on a nonnegative least squares (NNLS) solver that is very simple to code and ...
