1. File description
buildvptree.c --> main program for building vp-tree
knnsearch.c --> main program for k-nn search with vp-tree
vptree.c --> functions for building and searching
vptree.h --> common data structure and global variables
qsort.c --> qsort and bubble sort functions
qsort.h
standard.h
Makefile --> compile buildvptree and knnsearch
README --> this file
2. Compilation
type: make
3. Usage
type: buildvptree --> this will displays the usage of buildvptree
type: knnsearch --> this will displays the usage of knnsearch
4. Special variable setting
You may need to change the following values for your experiments.
_NUM_CAND_VP (vptree.h) --> no. of candidate VPs for the VP selection
_NUM_PT_RANDOM_SUBSET (vptree.h> --> min. no. of points in random subset for the VP selection
_MAX_POINTS_NODE (vptree.h) --> Maximum number of points in a node
_MIN_POINTS_NODE (vptree.h> --> Minimum number of points in a node
