* Qboid gives egg|z|egg an alpha motor
<egg|zzz|egg> UmbralRaptor: a turbine where the working fluid is α particles
<UmbralRaptor> I'm going to assume that for some reason we have 2 electrons for every alpha, and they keep on recombining on us, so it's not really a plasma.
<egg|zzz|egg> UmbralRaptor: from the methods section of the TRAPPIST paper: ""Initial assessment of the system’s long-term stability. We investigated the longterm evolution of the TRAPPIST-1 system using two n-body integration packages: Mercury52 and WHFAST57. We started from the orbital solution produced in Table 1, and integrated over 0.5 million years (Myr). This corresponds to roughly 100 million orbits for planet
<egg|zzz|egg> b. We repeated this procedure by sampling a number of solutions within the 1σ intervals of confidence. Most integrations resulted in the disruption of the system on a 0.5-Myr timescale.""
<egg|zzz|egg> uh, that's perhaps too many quotes
<UmbralRaptor> The compiler will disrupt that line on a 0.5 s timescale.
<egg|zzz|egg> UmbralRaptor: I should try replicating this stuff, this seems right up principia's alley; problem is finding the solutions fitting the observations
<egg|zzz|egg> UmbralRaptor: that's a 68 dof minimization problem
<egg|zzz|egg> UmbralRaptor: and I don't know how to do these things
<egg|zzz|egg> can somebody around here into high-dimensional minimization problems
<egg|zzz|egg> ?
<UmbralRaptor> Uh, something like ameoba simplex might be simplest?
<egg|zzz|egg> ???
<egg|zzz|egg> "We used two different minimization techniques: Levenberg–Marquardt55 and
<egg|zzz|egg> Nelder–Mead"
<egg|zzz|egg> apparently that's the second one?
* egg|zzz|egg never did any minimization
<UmbralRaptor> The "best" way involves baysian methods I don't understand presently. But the idea is that you run a solution with some set of parameters, you vary each parameter seperately, and then you look at which ones minimized things and go that way.
* egg|zzz|egg is a mathematician, not an astronomer (dammit jim)
<egg|zzz|egg> UmbralRaptor: sounds intuitive enough
<egg|zzz|egg> UmbralRaptor: how do you avoid local minima
<egg|zzz|egg> I've heard about simulated annealing/simulated quantum annealing at some point
<UmbralRaptor> egg|zzz|egg: with that? You don't for the most part. There are things with guessing step size based on slope, and kicking around the solution a bit, but local minima are a problem.
<UmbralRaptor> IIRC
<UmbralRaptor> Not sure on the details of how annealing type things work.
<egg|zzz|egg> !tell whitequark https://en.wikipedia.org/wiki/Rosenbrock_function banana function
<Qboid> egg|zzz|egg: I'll redirect this as soon as they are around.
<UmbralRaptor> Uh, in some cases you may have other ways of exploring the solution landscape. eg: runs with widely seperated parameters.
<egg|zzz|egg> UmbralRaptor: hmm, so this does global but approximately? odd https://en.wikipedia.org/wiki/Simulated_annealing
<egg|zzz|egg> but it's for discrete problems? hmm
<UmbralRaptor> Slowly reducing the step size, but using random directions?
