Are Ranking trees pruned when nodes are given zero weight?

Hi,

While evaluating a complex ranking system, I gave some nodes a zero weight. As a side-effect, I expected this to speed-up the ranking process.

I don’t think I saw that happen.

So are zero weighted nodes pruned from the ranking tree? I realize that there’s a special case when all nodes are given zero weight, but that shouldn’t prevent tree pruning. Right?

They are not… i’ve wondered why in the past.

It’s really should . I saw lots of huge ranking systems with 0 nodes as place holders. Not a use case we thought about

Thanks

I have several factors that I have set to 0, do I understand that removing them will speed up the ranking process?

All 0 nodes (besides the ones when “I realize that there’s a special case when all nodes are given zero weigh”) is a drag on the speed of the ranking system, and simulations?

I’d like to know more about this too. If someone were to have several hundred nodes and 95% of them are zero, does that dramatically slow down a simulation?
