Search for a minimum of Easom's function
F(X1,X2) = -cos(X1)*cos(X2)*exp(-(X1-pi)^2 - (X2-pi)^2)
from the starting point with coordinates X1=2, X2=2.
The search is unconstrained.
The function has a minimum at X1=pi, X2=pi. Value of the function in this minimum is equal to -1.

# Code of the optimized function:
- cos({1}) * cos({2}) * exp(-pow({1}-pi,2) - pow({2}-pi,2))
# Type of the optimization (1 - search for a maximum, -1 - search for a minimum):
-1
# Boundaries (on left and right) and starting point coordinates (middle) separated by comma. If a boundary is absent, a comma MUST BE PRESENT.
