C# 클래스 Cureos.Numerics.IpoptProblem

Function for adding a floating point option.

Function for adding an integer option.

Function for adding a string option.

Implement the IDisposable interface to release the Ipopt DLL resources held by this class

Constructor for creating a new Ipopt Problem object using native function delegates. This function initializes an object that can be passed to the IpoptSolve call. It contains the basic definition of the optimization problem, such as number of variables and constraints, bounds on variables and constraints, information about the derivatives, and the callback function for the computation of the optimization problem functions and derivatives. During this call, the options file ipopt.opt is read as well.

Constructor for creating a new Ipopt Problem object using managed function delegates. This function initializes an object that can be passed to the IpoptSolve call. It contains the basic definition of the optimization problem, such as number of variables and constraints, bounds on variables and constraints, information about the derivatives, and the callback function for the computation of the optimization problem functions and derivatives.

Method for opening an output file for a given name with given print level.

Setting a callback function for the "intermediate callback" method in the optimizer. This gives control back to the user once per iteration. If set, it provides the user with some information on the state of the optimization. This can be used to print some user-defined output. It also gives the user a way to terminate the optimization prematurely. If the callback method returns false, Ipopt will terminate the optimization. Calling this set method to set the CB pointer to null disables the intermediate callback functionality.

Optional function for setting scaling parameter for the NLP. This corresponds to the get_scaling_parameters method in TNLP. If the pointers x_scaling or g_scaling are null, then no scaling for x resp. g is done.

Function calling the IPOPT optimization algorithm for a problem previously defined with the constructor. IPOPT will use the options previously specified with AddOption for this problem.

Dummy implementation of the managed objective function evaluation delegate. Recommended action is to override this method in a subclass and use the protected constructor of this base class to initialize the subclassed object.

Dummy implementation of the managed constraints evaluation delegate. Recommended action is to override this method in a subclass and use the protected constructor of this base class to initialize the subclassed object.

Dummy implementation of the managed objective function gradient evaluation delegate. Recommended action is to override this method in a subclass and use the protected constructor of this base class to initialize the subclassed object.

Dummy implementation of the managed Hessian evaluation delegate. Recommended action is to override this method in a subclass and use the protected constructor of this base class to initialize the subclassed object.

Dummy implementation of the managed Jacobian evaluation delegate. Recommended action is to override this method in a subclass and use the protected constructor of this base class to initialize the subclassed object.

Dummy implementation of the managed intermediate callback method delegate. Recommended action is to override this method in a subclass and use the protected constructor of this base class to initialize the subclassed object.

Dispose(bool disposing) executes in two distinct scenarios. If disposing equals true, the method has been called directly or indirectly by a user's code. Managed and unmanaged resources can be disposed. If disposing equals false, the method has been called by the runtime from inside the finalizer and you should not reference other objects. Only unmanaged resources can be disposed.

Constructor for creating a subclassed Ipopt Problem object using managed or native function delegates. This is the preferred constructor when subclassing IpoptProblem. Prerequisite is that the managed/native optimization function delegates are implemented in the inheriting class. This function initializes an object that can be passed to the IpoptSolve call. It contains the basic definition of the optimization problem, such as number of variables and constraints, bounds on variables and constraints, information about the derivatives, and the callback function for the computation of the optimization problem functions and derivatives. During this call, the options file ipopt.opt is read as well.
