A metric space secondary index, based on the M-tree, implemented according to the following paper:
Shichao Jin, Okhee Kim, Wenya Feng: MX-tree: A Double Hierarchical Metric Index with Overlap Reduction. ICCSA (5) 2013: 574-589
- C++ implementation
- object oriented programming
- based on the Gist library (http://gist.cs.berkeley.edu/)
-
deduplicate the building dataset before constructing the index.
-
set the super node's maximum size X10 of a usual node's size.
