True, because the broken line gives you the ability to cross and pass, with the solid line you are not allowed to pass.
Answer:
Yes
Explanation:
A nonlinear optimization problem is indeed a optimization problem in which there are nonlinear elements involved either as the objective function or one or more constraints may be nonlinear also. Let me show you an example. Let optimize de following function:

These are the constraints:

The last constraint consists on nonlinear elements, so this problem in fact a nonlinear optimization problem.
