Private Member Functions
Methods to block default compiler methods.
The compiler automatically generates the following three methods. Since the default compiler implementation is generally not what you want (for all but the most simple classes), we usually put the declarations of these methods in the private section and never implement them. This prevents the compiler from implementing an incorrect "default" behavior without us knowing. (See Scott Meyers book, "Effective C++")

Detailed Description

Base class for boundary control problems with Dirichlet boundary conditions, as formulated by Hans Mittelmann as Examples 1-4 in "Optimization Techniques for Solving Elliptic Control Problems with Control and State Constraints.

Part 2: Boundary Control"

Here, the control variables are identical to the values of y on the boundary, and therefore we don't need any explicit optimization variables for u.
