|
|
log(N) time by splitting a data set iteratively across, eg for 3
|
|
dimensions, dimensions x,y,z,x,y,z<p>In KDTREE-JTK, data are stored in block arrays instead of linked
|
|
structures, for minimal (usually zero) consing and allocation
|
|
overheads.<p>Balancing is done in-place with Wirth's median partition method, so it
|
|
should be fast and memory efficient.<p><p>By default, all floats are double precision, but this can be
|

changed in kdtree-jk-structs.lisp<p><a href="https://github.com/jetmonk/kdtree-jk">Access on GitHub</a><p><hr>
