Best ResponseYou've already chosen the best response.0to get the unit vector? Since the max increase is in the same direction as the gradient?

Best ResponseYou've already chosen the best response.1well, the gradient is the maximum direction of change; could be increase or decrease

Best ResponseYou've already chosen the best response.0so how do you know if it's increase or decrease?

Best ResponseYou've already chosen the best response.1I'm actually not too sure in this case. You could do it with multivariable max/min techniques if you know them.
