Geometry optimization is then a mathematical optimization problem, in which it is desired to find the value of r for which e(r) is at a local minimum, that is, the derivative of the energy with respect to the position of the atoms, ∂e/∂r, is the zero vector and the second derivative matrix of the system, (∂ ∂ ∂), also known as the hessian matrix, which describes the curvature of the pes at r, has all positive eigenvalues (is positive definite).

Many students don’t realize that an optimization problem is really a max/min problem; it’s just one where you first have to develop the function you’re going to maximize or minimize, as we did in stage i above. Having done that, the remaining steps are exactly the same as they are for the max/min problems you recently learned how to solve.

A number of algorithms for other types of optimization problems work by solving lp problems as sub-problems. Historically, ideas from linear programming have inspired many of the central concepts of optimization theory, such as duality, decomposition, and the importance of convexity and its generalizations.
We prove that it is np-complete to find a minimum weight polygon or a maximum weight polygon for a given vertex set, resulting in a proof of np-completeness for the corresponding area optimization problems. We show that we can find a polygon of more than half the area ar(conv(p)) of the convex hull conv(p) of p, and demonstrate that it is np-complete to decide whether there is a simple polygon of at least (3/2 + ε)ar(conv(p)).
