curve B
B1--------------------------B0
You define distances:
|A0 B0|
|A0 B1|
|A1 B0|
|A1 B1|
And find the smallest one. Then, based on the number of the shortest distance:
Flip A, Leave B
Flip A, Flip B
Leave A, Leave B
Leave A, Flip B
A more advanced metric would be to create all 4 blends, then pick the one that is shortest. Maybe that works better for what you want, maybe not.

ts will basically be a set of different ellipses:{a1, a2, b1, b2} (with different properties) From that i want to create random Lists of let’s say 15 items (ellipses) Something like that {a1, b2, b1, a1, a2, b1, b1, a2, a1, b1, b2, a1, b2, a1, a1}. But I want to be able to create some constrains. So for example if I have a1 I will be able to have next a2 or b1 but not to b2. I am not sure if this is possible in grasshopper and i was messing around with some logic components but without any luck.
Any help will be greatly appreciated.

nologically label them (there are currently 65 points and this is labelled as in the file i've attached). However, what i'm actually after is to reformat these points into an x and y style grid.(a1, a2, a3, a4, a5)(b1, b2, b3, b4, b5)(c1, c2, c3, c4, c5)(d1, d2, d3, d4, d5) etc.Any ideas/help how this can be made possible would be great.Thanks in advance…

Obviously you can skip the creation part and instruct GH to deal with instance definitions already listed in the Block Manager (say: find the block named "cell666_B3" blah, blah) ... but that means that you can only use them (meaning a rather "limited" parametric approach) and not make them from scratch (meaning a true parametric approach).
But I guess that you've tried the block way in the Rhino environment already. That said I use rather solely this approach in GH and yields quite manageable object collections - I would say "real-time" response (up to 20K instances) but I use dedicated Xeon E5 1630 V3 workstations (with NVida Quadros K4200 and up for the graphic response part of the equation) so the "performance" is rather a subjective thing.
Modifications:
easily doable with GH (on instance definitions at placing time: since you need only to scale them and not vary their topology).
Anyway post a portion of the R file.…
FORE MeshMachine (rather better) or after
BTW: For a mesh with 7M points ... well... you'll need some proper CPU to deal in a reasonable amount of time (what about a Xeon E5 1630 V3?).
Alternatively find a friend who knows very well Modo ... and see first hand what the US Movie Industry is all about.…
m b1 As Brep = Nothing
If (heights(b) > heights(b+1)) Then
b0 = breps(b+1)
b1 = breps(b)
Else
b0 = breps(b)
b1 = breps(b+1)
End If
Dim bDiff As Brep() = Brep.CreateBooleanDifference(b0, b1, 0.1)
If (bDiff IsNot Nothing) AndAlso (bDiff.Length > 0) Then
breps(b) = bDiff(0)
End If
