The function
f(X, Y) = 3(1 - X)2e(- X2-(Y+1)2) €“ 10(x/5 €“ X3 €“ Y5)e(-X2 €“ Y2) €“ e(-(X+1) €“ Y2)/3
was used to generate Figures (a) and (b) in order to illustrate the concept of local optima versus global optima.
FIGURE (a)
A FUNCTION WITH LOCAL MAXIMAAND MINIMA

FIGURE (b)
ANOTHER VIEWPOINT OF A FUNCTION WITH LOCAL MAXIMUMS
AND MINIMUMS

a. Minimize this function using LINGO.
b. Now minimize this function using LINGO with the Global Solver option turnedon.
