Sequent - Rules


Most proof systems provide ways to deduce one sequent from another. These inference rules are written with a list of sequents above and below a line. This rule indicates that if everything above the line is true, so is everything under the line.

Famous quotes containing the word rules:

    The great challenge which faces us is to assure that, in our society of big-ness, we do not strangle the voice of creativity, that the rules of the game do not come to overshadow its purpose, that the grand orchestration of society leaves ample room for the man who marches to the music of another drummer.
    Hubert H. Humphrey (1911–1978)

    A man often thinks he rules himself, when all the while he is ruled and managed; and while his understanding directs one design, his affections imperceptibly draw him into another.
    François, Duc De La Rochefoucauld (1613–1680)

    Here was a place where nothing was crystallized. There were no traditions, no customs, no college songs .... There were no rules and regulations. All would have to be thought of, planned, built up, created—what a magnificent opportunity!
    Mabel Smith Douglass (1877–1933)
