Swiss Ephemeris / Nelder-Mead simplex

[Laeeth Isharc via Digitalmars-d-announce]

Last one for a while, I think.  I wish you all a very peaceful 
Christmas and New Year, and let's hope 2015 brings some more 
positive energy to the world.

1. D bindings/wrappers for the swiss ephemeris

http://www.astro.com/swisseph/swephinfo_e.htm
"The SWISS EPHEMERIS is the high precision ephemeris developed by 
Astrodienst, largely based upon the DExxx ephemerides from NASA's 
JPL . The original release in 1997 was based on the DE405/406 
ephemeris. Since release 2.00 in February 2014, it is based on 
the DE431 ephemeris released by JPL in September 2013".

NB - Swiss Ephemeris is not free for commercial use.

2. D port of simple Nelder-Mead simplex minimisation (written by 
Michael F. Hutt in original C version) here.  With constraints.  
 From Wiki:

https://en.wikipedia.org/wiki/Nelder-Mead_method
"The Nelder–Mead method or downhill simplex method or amoeba 
method is a commonly used nonlinear optimization technique, which 
is a well-defined numerical method for problems for which 
derivatives may not be known. However, the Nelder–Mead technique 
is a heuristic search method that can converge to non-stationary 
points[1] on problems that can be solved by alternative methods".
