(a) Use an exhaustive search to solve this problem.
(b) Use a local search method to solve this problem. First, define the search space and the neighbourhood.
Then, attempt to find the minimum starting from the initial point
(x, y) = (2,0).
The neighbourhood of a point should contain at least two distinct points but must not encompass
the entire feasible search space. Will your local search method find the global optimum?
