Topic: Dispatch component implementation
e possible to change the component definition making possible to customize the number of outputs.Now Dispatch moves "true" values to A and "False" values to B INPUT: L (List to work on) -> 1, 2, 3, 4, 5, 6, 7, 8 D (Dispatch Pattern) -> True, False OUTPUT: A (List) -> 1, 3, 5, 7 B (List) -> 2, 4, 6, 8 Could it be possible/useful to modify it so it could dispatch items to several outputs, like: INPUT: L (List to work on) -> 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 D (Dispatch Pattern) -> A, B, C OUTPUT: A (List) -> 1, 4, 7, 0 B (List) -> 2, 5, 8 C (List) -> 3, 6, 9 maybe I'm missing something and there's already a component with this function... I have been searching on the forum for half afternoon, but can't find anything about it! Thank you!…

Topic: What are random seed values?
t, let's talk about randomness. Randomness is a problem in computing because digital computers are deterministic. If you give them the exact same instructions they always end up with the exact same result. It turns out to be mathematically impossible to generate true random numbers using a digital computer, but it is fairly easy to generate pseudo-random numbers. This is actually not bad news as pseudo-random numbers -unlike real random numbers- can be generated again and again and you'll end up with the same random numbers every time. Being able to get the same random numbers on demand increases the reliability of these number sequences which in turn makes them easier to use. Pseudo-random numbers are numbers that have certain characteristics. Note that when we talk about random numbers we are really talking about numbers. Plural. It's easy to generate only a single one, as xkcd so eloquently put it: So what are these characteristics that define pseudo-randomness? Without being actually correct, I can sum them up as follows: The sequence of generated numbers should never repeat itself* The numbers in the sequence ought to be spread evenly across the numeric domain** There are a lot of different algorithms out there, some better than others, some faster than others, some solving very specific problems while others are more generic. The generator used in Grasshopper is the standard Microsoft .NET Random, based on Donald Knuth's subtractive algorithm. So let's imagine we want random integers between 0 and 10. What would a bad random sequence look like? 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3  (about as bad as it gets) 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9  (not random at all) 1 3 2 5 3 9 1 2 4 2 5 1 1 2 8 1 5 2 3 4  (too many low numbers) 2 8 4 6 0 9 8 2 4 8 6 4 2 2 5 1 4 8 6 2  (too many even numbers) So what about good sequences? Well, here's a few: 6 9 1 2 0 4 2 8 5 7 2 9 1 9 2 5 3 1 9 2  (sure, why not) 6 2 5 3 4 1 9 7 8 0 2 1 6 4 5 8 9 5 0 9  (looks about right) 1 8 5 2 3 4 5 7 9 5 2 1 0 2 1 0 9 7 6 4  (I suppose) 9 0 6 4 8 3 1 5 2 7 6 1 4 6 0 1 9 7 5 6  (whatever) There are a lot of valid pseudo-random sequences. (Seriously, loads). So even if we have a good pseudo-random generator we may be given a random sequence that isn't entirely to our liking. The shorter the sequence we need, the more likely it is that statistical aberrations invalidate that particular sequence for us. What we need is some control over the generator so we don't just get a repeatable sequence, but a repeatable sequence we actually like. Enter seed values. The random generator requires a seed value before it can generate a random sequence. These seed values are always integers, and they can be any valid 32-bit integer. Every unique seed value results in the same sequence. Every time. Unfortunately there is no clear relationship between seeds and sequences. Changing the seed value from 5 to 6 will result in a completely difference random sequence, and two sequences that are very similar may well have to wildly different seeds. There is therefore no way to guess a good seed value, it is completely trial-and-error. Also because of this extremely discontinuous nature, you cannot use tools like Galapagos to optimize a seed value. If you are looking for a pseudo-random sequence which has custom characteristics, you may well end up having to write your own generator algorithm. Ask questions about this on the Grasshopper main forum or the VB/C# forum. Conclusion: Seed values are integers that define the exact sequence of pseudo-random numbers, but there's no way of knowing ahead of time what sequence it will be and there's no way of tweaking a sequence by slightly changing the seed. Even the tiniest change in seed value will result in a radically different random sequence. -- David Rutten david@mcneel.com Poprad, Slovakia * This is not actually possible. A finite amount of numbers always repeats itself eventually. ** This should only be true for long enough sequences, short sequences are allowed to cluster their values somewhat.

Comment on: Topic 'Help Please! Sorting Lists into subsets for manipulation'
Looks good, How can I then select those circles as a branch? For example, I want to divide all the Radius 3 circles into 8 parts, all radius 9 into 6 parts etc. Many Thanks for your help

Comment for: Bill Chow
其实也没用在什么固定的地方,只是作为一个工具用在适合的地方。之前用来做参数化的幕墙设计,现在在做建筑能耗模拟方面的工作,就在开发一个grasshopper插件来帮助完成大量的计算工作,暂时没和几何扯上关系,只是通过grasshopper运行外部程序而已,可能稍后会结合起来,方式最后可能和geco有点类似。主要是用惯了grasshopper,一直还在边做边学的阶段。

Comment on: Topic 'closest point, intersection'
a follow up question... how do I wrap a list onto itself at a certain frequency? i.e.  I want the list {1;2;3;4;5;6;7;8;9}       to become {1,4,7; 2,6,8; 3,6,9}  wrapped every 3rd item
