  1. #kdtree and ball trees seem cool, but require full knowledge of the thing I'm searching for. What if it's 7 dimensional and I only know 4 of the values?

    I feel like a "parallel kd tree" with a separate binary index on each dimension would work better here.

    Reduce depth. Allow unspecified values. It'd also be a snap to create and search each dim in parallel.

    This must already exist...

  3. By using a #KDTree the calculation time goes down from 5.75 to 1.0 seconds #CreativeCoding

  5. Randomly stumbled into #kdtree #quadtree #algorithm today and it happened to allllmost line up with a work problem I've been pondering.

    My problem involves moving objects. Not just moving, but I want to query them at different points in time.

    I think if I just add a time dimension (HexTrees?) it might work...? I'm not clear on the details of the actual algorithm or how this would work. #software #math
