deterministic
     
        1.  Describes a system whose time evolution can
        be predicted exactly.
     
        Contrast {probabilistic}.
     
        2.  Describes an {algorithm} in which the correct
        next step depends only on the current state.  This contrasts
        with an algorithm involving {backtracking} where at each point
        there may be several possible actions and no way to chose
        between them except by trying each one and backtracking if it
        fails.
