What are the current results?
Closed this issue · 7 comments
Do we have any progress on getting smoother solutions? Any new results to show?
Do we have any idea if we are closer to getting global instead of local solutions?
If so, it'd be great to share the figures with the new results. If not, what's the status?
In the latest commit on master I see:

So whatever test you are running is solving. Are these the noisy solutions still, or now smooth?
Do we have any progress on getting smoother solutions? Any new results to show?
Not yet. I'm working on this but it's requiring me to understand and rework Jan's code which is taking a while.
Do we have any idea if we are closer to getting global instead of local solutions?
No idea yet. Will know when I finish reworking the model and we are able to solve successfully.
If so, it'd be great to share the figures with the new results. If not, what's the status?
I will circulate the results as soon as I'm able to generate them.

These are still the results from Jan's thesis so are still noisy and multimodal.
Ok. We soon need to make the call to go with Jan's original results. How about a March 31st deadline to make the call? We are now about a month behind the original idea of having a paper prepared by the end of February.
Yes, I appreciate the time pressure. Can I please request 9th April as I'm away on vacation 25th March - 2nd April which would otherwise only give me another couple of hours on it this evening? I'll make this my top and only priority for work outside of work hours until then. If I have anything sooner than that, even if it's just an indication of progress, I'll update you both.
It shouldn't be work outside of work. I think you, Jan, and I should touch base ASAP. Maybe a call or something.

Agreed! let's try and schedule a quick meeting this week. Any date/time this week will do, except for Wednesday afternoon
We went back to Jan's original results.
