[MITgcm-devel] restarting an optimization

[Martin Losch]

Hi there,

rather than repeat the entire optimization, I'd like to restart one at some iteration, after resetting one of the control parameters. In my case, I want to modify xx_theta (initial conditions for theta). I thought that when I modifiy xx_theta.${iteration}.data while the adjoint model is running, ctrl_pack should use the modified version and pack it into the control vector that is read by optim.x
However, the result is discouraging: nothing substantial changed. What else do I need to reset such an iteration? Force a cold start by the optimizer?
