Unnoised

The silent, the unnoised, unrecorded acts of goodness of Sir Francis Darrell broke suddenly upon us at almost every turn […]

Now the program calculates the coordinates of the point along the unnoised exit beam vector which has the noised range from the sensor; this is the point the sensor's software believes it has detected.

The first variant consists in alternating noised phases with unnoised descents. More precisely, in order to stay closer to the original function f, we may apply a given number v of elementary transformations with respect to the noised function f_(noised), then a descent with respect to f until a local minimum is reached, then again v noised trials, then a descent with respect to f, and so on.
