The Smaller and Generalized Alignment Indices methods are robust techniques that can distinguish chaotic behavior from regular, or stable periodic orbits from unstable ones, efficiently.
These effi…

Currently I am drawing from the following distributions (mu, sigma) for the transit times of each of the TRAPPIST-1 planets:
```python
transits = [(7322.51736, 0.00010),
(7282.80728,…

Hello Dan and co.,
great work on emcee!
Is there a recommended way, or even a hack, to treat periodic model parameters?
I'm thinking about phases, sky positions, etc. It's not a problem to make the…

Consider the IVP `y' = y` with `y(0) = 1`. Since we know `y(1) = e`, let's check `ode45`:
```julia
julia> using ODE
julia> t, y = ode45((t, y) -> y, 1.0, 0:0.1:1; reltol=eps(), abstol=0.0)
([0.0…

When dealing with, say, periodic orbits, braids could be checked for "cyclic equality", meaning they are the same no matter where you start in the cycle. It would be nice to implement this in a "cycl…

Need doing:
- [x] Fix `sin` and `cos` problem so that Newton works
- [x] Newton that terminates when it should terminate, not with a fixed number of iterations
- [x] Make Interval, AD and Newton into …

The GADGET 2 Makefile controls much of the functionality of GADGET. Apart from the input parameter file, this file (the Makefile) needs to be sent with the job input sandbox at runtime, so that GADGET…
