3.1 The Maximum Entropy Method » Quiz 2 Solution
1. The answer is c. This is the point where the constraint contour is parallel to the function contour, which, as Simon explains in the video, is the maximum of f subject to constraint g.
2. The answer is d. The contours of f and g are parallel. This makes the gradients of f and g also parallel which makes the perpendiculars to the gradients of f and g parallel.
