SMiles ARbitrary Target Specification (SMARTS) is a language for specifying substructural patterns in molecules. The SMARTS line notation is expressive and allows extremely precise and transparent substructural specification and atom typing.
SMARTS is related to the SMILES line notation that is used to encode molecular structures and like SMILES was originally developed by David Weininger and colleagues at Daylight Chemical Information Systems. The most comprehensive descriptions of the SMARTS language can be found in Daylight's SMARTS theory manual, tutorial and examples. OpenEye Scientific Software has developed their own version of SMARTS which differs from the original Daylight version in how the R descriptor (see cyclicity below) is defined.

Famous quotes containing the words smiles, arbitrary and/or target:
“I live for those who love me,
Whose hearts are kind and true;
For the Heaven that smiles above me,
And awaits my spirit too;
For all human ties that bind me,
For the task by God assigned me,
For the bright hopes yet to find me,
And the good that I can do.”
—George Linnaeus Banks (1821–1881)
“The arbitrary division of one’s life into weeks and days and hours seemed, on the whole, useless. There was but one day for the men, and that was pay day, and one for the women, and that was rent day. As for the children, every day was theirs, just as it should be in every corner of the world.”
—Alice Caldwell Rice (1870–1942)
“Well gentlemen, this is it. This is what we’ve been waiting for. Tonight your target is Tokyo. And you’re gonna play ‘em the Star Spangled Banner with two-ton bombs. All you’ve got to do is to remember what you’ve learned and follow your squadron leaders. They’ll get you in, and they’ll get you out. Any questions? All right that’s all. Good luck to you. Give ‘em hell.”
—Dudley Nichols (1895–1960)
