at your original list of numbers, if I am to go through and check manually to see what I should be getting out, I think you should only get a few outputs (which is why I was confused by all the outputs at the end of the definition.
For example, just as an example I started with X1 as 279 (item index 11). When I did the math, the only indexes that I got were 15,28, and 33.
This is because:
since 279 is positive, look for next number that is at least 180 less or 360 more than X1.
the value of 78 (item index 15) is the first value to satisfy this requirement.
Then, since 78 is smaller than 279, we are looking for the next value at least 180 more or 360 less than 78.
The value 272 (item index 28) is that next value.
Then since 272 is larger than 78, we are looking for the next value at least 180 less or 360 more than 272.
The value 52 (item index 33) is the next value.
So the definition should output the following:
indexes 15, 28, 33.
Does that make sense?…

l equations that describe his attractor in a chaotic behavior when rho > 24.7. All the values of X =sigma(Y-X) *dt never repeat themselves through each moment in time making their distribution totaly random, we can see this at the end of the video with the linear graph. The beautiful thing is that even though the values of X are randomly distribuited over time, the result is a beautiful ordered shape, this in essence is the principal of chaotic systems. Or as James Gleick would say " chaotic systems embed hidden ordering principles"
X =sigma(Y-X)
Y= -X*Z+rho*X-Y
Z = X*Y-betta*Z
X = dx/dt -------> change of X over time
Y = dy/dt -------> change of Y over time
Z= dz/dt -------> change of z over time
rho = 28
betta = 3/8
sigma = 10

he canvas redrawing and the Rhino viewport redrawing take some time as well (on my system 6 ms for the empty Gh canvas and 28 ms for the empty Rhino viewport). No timer can avoid that, to my knowledge. The trampoline computes timing after the solution is complete. This means that one cycle is: solution completed + drawn + user specified interval.
Hope that this helps to get started,

error message when GH starts loading (almost the last stage of loading).
I un-installed and re-installed it, but still the same error. When I checked the plug-ins in the options, it seems that it is loading the right one (from the file path), but I noticed when GH starts loading, it is loading GH version Sep 28, 2012.
Any idea how I can get around this problem?
thanks

ay be loading it from Rhino 4, but even when I un-installed GH for Rhino 4, GH rhino 5 still loading that version. The strange thing is that when I check Tools-options-plug ins, GH -properties it shows the right file name and path of GrasshopperPlugIn.rhp, and the right registry path too that is in Rhino 5 Plug ins. So why on earth it is loading that previous mysterious copy?, and where it can be located?
Any steps I need to follow that may solve the problem?…

Delaunay triangulations maximizes the minimum angle of all the angles of the triangles in the triangulation; they tend to avoid skinny triangles.
In order to obtain a valuable (quality) mesh at a given minimum angle for triangles (here 15 degrees), I advise to implement Chew Second Algorithm (see : http://2011.cccg.ca/PDFschedule/papers/paper91.pdf).
Then, the control of triangle lengths should be done by pruning edges below 28 inches.
Do not hesitate to contact me.…
stricts). This will tell me which properties within the set exist in more than one zone.
I've gotten this far, but cant seem to get a set of all the property lines that are crossed by zoning lines. From using GIS, I know the answer should contain 28 properties.
I've attached what I've done so far, any help would be appreciated.

another comma separated txt file. I know how to import points (function Import coordinates), but I dont know how to connect them by lines if the only information I have about lines is the list of point numbers which should be connected. The txt file with point coordinates looks like:
-18,-36,-1000-18,-34,-19.728-18,-32,-17.603-18,-30,-15.372-18,-28,-13.121
...
And the txt file with line connections looks like:
1,22,33,44,55,6
...
Which means that I want to connect point 1 with point 2, point 2 with point 3 etc...
Both txt files are attached, thank you for the answer...…
