 Without an objective, a vast number of solutions can be feasible, and therefore to find the "best" feasible solution, military-specified "ground rules" must be used that describe how goals can be achieved as opposed to specifying a goal itself.Dantzig's core insight was to realize that most such ground rules can be translated into a linear objective function that needs to be maximized.Development of the simplex method was evolutionary and happened over a period of about a year.
