-This directory contains the sample script [sample_run.sh](sample_run.sh) as well as scripts to re-produce most of our results. To run the sample script without drawing plots type:
-```
-./sample_run.sh 0
-```
-To run sample experiments **AND** plot performance plots, type:
-```
-./sample_run.sh 1
-```
-Note that plots generating software requires Python, Latex, and PGF.

 Scripts to reproduce our previous results are in subdirectories [sisap2013](sisap2013), [nips2013](nips2013), [da2014](smallworld_Apr2014), and [vldb2015](vldb2015).
 Notes on reproducibility:
-* All scripts except for **vldb2015** should use binaries from [the previous release](https://github.com/searchivarius/NonMetricSpaceLib/releases/tag/v1.0).
-* The current release contain implementations of proximity graphs that are actually more efficient than those used for vldb2015 paper. 
+* All scripts except for **vldb2015** should use binaries  [version 1.0](https://github.com/searchivarius/NonMetricSpaceLib/releases/tag/v1.0).
+* **vldb2015** should use use binaries [version 1.1](https://github.com/searchivarius/NonMetricSpaceLib/releases/tag/v1.1). 
 
-In the case of light-weight distance, e.g., L2, the new implementations are about 3 times as efficient as the old ones. However,
-in the case of expensive distances the difference is much less. In particular, in the case of the normalized Levenshtein distance, the improvement is only 30%. Nevertheless, the old versions are still present under the names ``small_world_rand_old`` and ``nndes_old``.
