Which of the following is a necessary condition for a local minimum of a nonlinear programming problem?

  1. The gradient of the objective function is zero.

  2. The Hessian matrix of the objective function is positive definite.

  3. The Lagrangian function is minimized.

  4. The Karush-Kuhn-Tucker conditions are satisfied.

Show answer
Correct Option: D
Explanation:

The Karush-Kuhn-Tucker conditions are a set of necessary conditions that must be satisfied at a local minimum of a nonlinear programming problem.

Which of the following is a common method for solving nonlinear programming problems?

  1. Linear programming

  2. Integer programming

  3. Dynamic programming

  4. Sequential quadratic programming

Show answer
Correct Option: D
Explanation:

Sequential quadratic programming is a common method for solving nonlinear programming problems. It is an iterative method that solves a series of quadratic programming subproblems.

What is the purpose of a penalty function in nonlinear programming?

  1. To transform a constrained problem into an unconstrained problem

  2. To improve the convergence of an optimization algorithm

  3. To reduce the number of iterations required to solve a problem

  4. To find a global minimum of a problem

Show answer
Correct Option: A
Explanation:

A penalty function is used to transform a constrained nonlinear programming problem into an unconstrained problem. This can make the problem easier to solve.

Which of the following is a common type of nonlinear programming problem?

  1. Convex programming

  2. Non-convex programming

  3. Linear programming

  4. Integer programming

Show answer
Correct Option: B
Explanation:

Non-convex programming is a common type of nonlinear programming problem. In a non-convex programming problem, the objective function or the constraints are not convex.

What is the difference between a local minimum and a global minimum in nonlinear programming?

  1. A local minimum is a point where the objective function is minimized in a neighborhood of the point, while a global minimum is a point where the objective function is minimized over the entire feasible region.

  2. A local minimum is a point where the objective function is minimized in a neighborhood of the point, while a global minimum is a point where the objective function is minimized over the entire feasible region.

  3. A local minimum is a point where the objective function is minimized in a neighborhood of the point, while a global minimum is a point where the objective function is maximized over the entire feasible region.

  4. A local minimum is a point where the objective function is maximized in a neighborhood of the point, while a global minimum is a point where the objective function is minimized over the entire feasible region.

Show answer
Correct Option: A,B
Explanation:

A local minimum is a point where the objective function is minimized in a neighborhood of the point, while a global minimum is a point where the objective function is minimized over the entire feasible region.

Which of the following is a common method for finding a global minimum of a nonlinear programming problem?

  1. Branch and bound

  2. Cutting planes

  3. Simulated annealing

  4. Genetic algorithms

Show answer
Correct Option: A
Explanation:

Branch and bound is a common method for finding a global minimum of a nonlinear programming problem. It is a systematic method that divides the feasible region into smaller and smaller subregions until the global minimum is found.
