Decide upon what to do stale mode_compute options
In the process of factorizing the optimization calls (see #800), we should clean up. Currently,
mode_compute==2,101,102 are broken/not supported anymore. 2 and 102 are non-existing simulated annealings. I would propose to drop 102 and replace 2 by Matlab's
simulannealbnd from the Global Optimization Toolbox. That way we would have at least one simulated annealing available.
I have no clue why we have the undocumented 101 which is
solveopt and would suggest to drop it.
