The CpNonLinearMethodType enumeration contains methods of optimal controlling problem calculation. This enumeration is used by the following properties and methods:
| Value | Brief description |
| 0 | GridSearch. Search by grid. Method of search by grid is one of direct minimization methods requiring a lot of computational costs and not used for solving practical problems. Result of this method is the extremum of the criterion function that is found by grid search where number of nodes is defined by the user. Precision of the found solution depends on the grid size. |
| 1 | SequentialQP. Sequential quadratic programming. This is a method with quadratic subtasks. Result of this method is a local extremum that is defined by initial approximations or the extremum of the function in case of non-linear variables constraints. |
| 2 | SequentialSimplex. Sequential simplex is a method of unconstrained optimization. Result of this method is a local extremum determined by initial approximation. |
| 3 | DifferentEvolution. Method of differential evolution. It is used to solve the optimal control problem. |
