The current NSGA-II multi-objective optimization algorithm is too fancy (slow and inaccurate) for optimizing recoils or fluence. A single-objective linear fit algorithm would run faster and probably yield similar results.

Objectives to optimize (simulated vs. measured values):

  • area
  • sum

Different local minimums could be presented for the user to select.

The options for algorithms could be displayed like this:

  • NSGA-II (slow)
  • Linear (fast)

- the button doesn't affect optimization yet

First version is implemented, but this is not complete yet. See #261 for remaining tasks.

@tpitkanen
Make linear optimization the new default (JYU-IBA#193)
e56fc25 
- this should be better than NSGA-II now
- opening the optimization dialog causes a brief flash now for some
  reason, probably related to the order of operations, or maybe the
  choose_optimization_method call

This is more complete now, but there are still some major things missing (#262).
