Implemented Index Structures

The qiuck start variant of QuEval contains only the sequential scan. To add more indexes, simply download of of the zip files below, copy and extract tham in the folder QuEval is located in. After restarting QuEval, looks for any .class file (via reflection) and adds all indexes in index/structures folder that extend from AIndexStructure.class to the list of available indexes. Currently, the following index structures are available within the QuEval framework.

Name	Java implementation	C-Sharp implementation	C++ implementation
QuEval	Quick start GUI - zipped German main memory variant. To change, edit Config.properties (Line 3 language, Line 5 switch between disk and main-memory based variant).
Pyramid technique	Source and binary - zipped
VA-File	Source and binary - zipped
Prototype-based approach	Source and binary - zipped
LSH-based approach	Source and binary - zipped
R-Variant (similar to GIST)	Source and binary - zipped
k-d Tree	Source and binary - rar
M-tree	Source and binary - zipped
Experimental indexes Currently under development
AESA	Source and binary - zipped
Parallel seq. scan	Early synchronization - rar Late synchronization - zipped

Supported metrics

By default, the Minkowski metric family (Manhattan, Euclidean etc.) is included. The following metrics are also implemented. For Java copy the zip-file in into the folder of QuEval and unzip the files. After restarting the framework the additional metrics are included.

Name	Java implementation	C-Sharp implementation	C++ implementation
Bray Curtis	Source and binary - zipped
Chi Square
Dynamical partial
Jeffrey
Quadratic
