One solution is
wincl.hbrBackground = CreateSolidBrush(RGB(202, 238, 255));
where WNDCLASSEX wincl is class.
This solution is improvident because for each window must be one class. Better is...

Combinatorial approach:
I have any idea:
If we have only one vertex - nothing to do
If we have connected 0 with 1 - let remove 0 or 1
If we have three vertices, we have 3 similar cases and one...

Original problem is:
I have set of points. I must decimate this points obtain subset points, where distance between each pair is >=dmin.
I use graphs giving connections between vertices if distance...

Sorry for my English, if the terminology will be confusing.
We have graph with vertices: 0..7
This vertices are connected bidirectional:
0 with 1
1 with 2
3 with 4
