Sigh. I’ve been through like 5 mailing lists and got trolled off each one. Let’s start simple
...plication to help with compiling and security. It’s like sudo but more secure and can chain. I don’t know much about pipes and streams, but I’m pretty sure I can write it into llvm with enough time and help.
Another thing, and I got trolled off gcc’s mailing list for this, we need multidimensional multidirectional binary tree functions, I call them graphs because someone on Usenet told me they replicate a graph since they work on multiple dimensions. Now this is memory intensive if you don’t implement rolling dma, I suggest something modularized into the kernel to save cpu cycles.
I understand xnu is writte...

any more direct-search optimization method in R
...elder
mead to minimize it but it is way too slow and the returned results are not
satisfying. simulated annealing is so hard to tune and it always crashes R
program in my case. I wonder if there are any packages or functions can do
direct search optimization?
A rough search in literature shows multidirectional search and DIRECT
algorithm may help. Is there any other satisfying algorithm?
Thanks,

geoR, plot of variog4 lines incomplete
...variog. I'm
using the same geodata for each plot.
I've attached 2 graphs to illustrate. The first is a plot of a 90-
degree directional variogram created using variog:
> trees90.vgm<-variog(trees.geo,max.dist=100,direction=pi/2)
> plot(trees90.vgm)
The second is a plot of a multidirectional variogram created using
variog4:
> trees.vgm4<-variog4(trees.geo,max.dist=100)
> plot(trees.vgm4)
The graphs are also available at:
www.tiem.utk.edu/~mmfuller/R_plots.pdf
You can see that the 90 degree line in the multi-line plot from
variog4 (dotted green line) does not include al...
