r12829 Created branch for testing runtime experiments with steepest descent

comment:2 Changed 6 months ago by randersson

r12832 Added a runtime experiment trying to converge with steepest after failing with newton

comment:3 Changed 6 months ago by randersson

r12836 Added minor modification utilizing central differences with steepest when the newton solver failed

comment:4 Changed 6 months ago by randersson

r12854 Minor cleanup, fixed identation and removed flag for central diffs.
r12855 Created new branch in order to test another runtime change from a clean workspace

r12909 Test of another experiment for convergence for specific scenarios

r12910 Merged trunk into branch

comment:7 Changed 5 months ago by randersson

r12987 Updated runtime changes to use correct value of step sizes and norms

comment:8 Changed 5 months ago by randersson

r13001 Made a minor modification to the value that is used to compared the absolute value of the step to. Did also made a minor fix of the output for the step size which was incorrectly printed to logfile du to a missing function call.

r13058 Minor adjustment in experiment, now choosing maximum of two values instead of always picking the nominal value. Also made a minor fix to get rid of some unnecessary prints.
