Index for Spatial Data Base with weight parameters?

A spatial index must satisfy the triangle inequality i.e. The graph has to be an euklidian space. I don't think you can put a weight on it nor that there is a database.

I have a feeling that specific data structure could accomplish this. I am looking for some kind of modification of an R-tree. – Coder Latvia 13 hours ago @CoderLatvia: There is spatial index for multi-dimension but that's not for optimizing problems i.e.Weights.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
