Algorithmic Model
     
         A method of estimating software cost using
        mathematical {algorithms} based on the parameters which are
        considered to be the major cost drivers.  These estimate of
        effort or cost are based primarily on the size of the software
        or {Delivered Source Instructions} (DSI)s, and other
        productivity factors known as {Cost Driver Attributes}.
     
        See also {Parametric Model}.
