Apparently something went wrong in the last step (the energy increased, which it shouldn't - but then this is a strongly nonlinear problem), which is also why the program aborted after this iteration. Apart from this, the iterations shown above demonstrate that our program indeed is able to reduce the energy in the solution in each iteration, as should be. -

+ + Since the program did not really deliver the goal we had originally intended for (the computation of the minimal energy of finite element spaces), the graphical output is also not very exciting. Here are plots of five of the first 10 solutions (clicking on a picture gives the unscaled version of the image): -

Note that this behavior is mostly independent of the choice of starting data (which we have chosen to be close to this curve), which a posteriori justfies our choice. Some of the curves actually show a linear behavior of the solution close to the origin; this is particularly obvious when the curves are viewed in a log-log plot (not shown here, but rather left as an exercise to the reader). -

+ + Given the almost complete absence of interesting results of this program, we hope that at least its source code provided some information with respect to programming with deal.II -
