Linkage determines what you can see across translation units. break points Taming software complexity BY JACK G. GANSSLE OO49 The increased use of variable-speed drive motors to reduce energy consumption will require a shift from PID controllers to systems based on fuzzy logic algorithms to simplify design, reduce development time, and eliminate complex math formulas. A simple equation can help you measure the complexity of your code.
