In mathematics, the rational sieve is a general algorithm for factoring integers into prime factors. It is essentially a special case of the general number field sieve, and while it is far less efficient than the general algorithm, it is conceptually far simpler. So while it is rather useless as a practical factoring algorithm, it is a helpful first step for those trying to understand how the general number field sieve works.

Famous quotes containing the words rational and/or sieve:
“There has never been in history another such culture as the Western civilization M a culture which has practiced the belief that the physical and social environment of man is subject to rational manipulation and that history is subject to the will and action of man; whereas central to the traditional cultures of the rivals of Western civilization, those of Africa and Asia, is a belief that it is environment that dominates man.”
—Ishmael Reed (b. 1938)
“They went to sea in a Sieve, they did,
In a Sieve they went to sea:
In spite of all their friends could say,
On a winter’s morn, on a stormy day,”
—Edward Lear (1812–1888)
