get this and more "spot-on" examples would follow.

Thank you peter for this definition, it is really interesting and I liked the way it's writen (visually it helps in reading and understanding the definition, which is not really common for other defintions...)

Any how, I would like that internal circles to be tangent to each other as well, without having interseted disks..), is there a way to do this?

Thank you again for your help and for this definition

Get these 2 as well (I was in office where we use internal C# stuff for packing things, not Kangaroo).

And ... well ... the hand grenade: see warnings (this is not for the inexperienced ... but it's relatively safe to use it on open breps).

Load R file first

PS: Obviously NOT any collection of circles (out of the blue, that is) can been packed with the tangent goal - hope that you accept this rather obvious "limitation".

best

Get 2 more (read instructions for the V06: it's a bit interactive - until Havoc occurs, he he. NOTE: do not use the option for random radii on that one ... it's something WIP that I have in mind).

All in all:

IMHO (and if you have a "cooperative" surface) the good old V47 can cut the mustard.

I was trying all theses definitions that I found really intelligent... I am new in grasshopper and I think I have a lot to learn to be able to think in a grasshopper way... Too many components and too many plugins... and it is going to be even more I think...

Anyhow, I am afraid that all the definitions you just showed here do not answer my request, and I am not sure if developping one of the previous definitions can... 

In all examples we are populating points in a rectangle or in a shape... well the nb of 2d populated  points can be managed, but what if I want to attribute for each point a circle with a fixed area and that these circles will fit in a given shape

Ex: I want to populated 7 circles in a shape (S)

Circles / Area:

C1/A1

C2/A2

C3/A3

C4/A4

C5/A5

......

The closed shape (S) will be the boundary of these circles not to depass (like obstacles), and circles must be tangent inside the shape (S)....

I do not have any idea of how complicated this might be, but I think more complicated stuff were resolved in grasshopper.

Again thank you for your time and consideration

Regards

Well ... give this a spin: https://www.google.gr/url?sa=t&rct=j&q=&esrc=s&sour...

BTW: Switching from K1/K2 to code based solutions: Packing algos are quite important these days for minimizing the waste when cutting panels etc etc. Therefore is quite rare to find the related code [i.e. a highly efficient one, that is] - but since McNeal provides the above [I haven't tested it, mind] ... try it.

I have used one of your definition that you provided previously, I have somehow adapted so I can manage the nb and size of packed circles... But I did not succeed to make the circle tangent... 

Do u mind if you take a look please on this?

Thank you in advance
