Consider the problem of minimising the Euclidean distance from the point (-4,5) in the plane to the set
of points (x, y) that have integer coordinates and satisfy the inequality:
x2
y²
+ ≤1.

(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?
Consider the relation ✓ on R² defined by
u ≤ v
u₁ + v₂+ 3u1 v² < u₂ + v³ + 3u²v₁

u = v
for any u, vЄR² with u = = (u1, u2), v = = (V1, V2).
