Procedure for Changing Parameter Range

[cancan101]

Allow for changing the range over which a given parameter is experimented.

This might "just work" now with main being restarted with a different range.

Similar to #35.

Unfortunately, this definitely will not work correctly if you restart main
with a different range. This would require either writing scripts to
extract the old range and create a new experiment or rewriting some of the
internals of spearmint.

Note that this is fixed in the new spearmint repo (https://github.com/HIPS/Spearmint)

Is this purely because the parameters are decoded with e.g.

variable['min'] + u[index]*(variable['max']-variable['min'])

[JasperSnoek]

Yes and the parameters and jobs are stored within the grid object in the
unit hypercube (encoded).

So in order to convert a saved pickle file, I would have to:
0) Stop all running jobs and stop main.py

1. Modify: expt-grid.pkl/vmap/variables
2. Rescale: expt-grid.pkl/grid
3. Change the: config.pb file

Is that it, or am I missing something?

[JasperSnoek]

Yeah I think that's it!
