fm.AddRule(FzAND(Target_Medium, Ammo_Okay), VeryDesirable);

fm.AddRule(FzAND(Target_Medium, Ammo_Low), Desirable);

Once a FuzzyModule has been initialized, it’s a painless matter to input val

ues and calculate a crisp conclusion. Here’s a method that does just that:

double CalculateDesirability(FuzzyModule& fm, double dist, double ammo)

{

//fuzzify the inputs

fm.Fuzzify("DistToTarget", dist);

fm.Fuzzify("AmmoStatus", ammo);

//this method automatically processes the rules and defuzzifies
