Ycart, F. Jacquemard, J. Bresson — UMR STMS Ircam/CNRS/SU, 2015-2016\n\n### The k-best parsing\n\nThe quantization algorithm is a recursive, dynamic-programming, lazy algorithm. It works by recursively subdividing segments into equal parts, and then aligning the input points to the closest segment boundary. The algorithm enumerates the subdivisions that give the best results, ranked according to a criterion that combines two quality measures :\n\n- Distance: how close the output is to the input. This distance is given by the sum of the differences between each input point and the point to which it is aligned.\n- Complexity: in other words, readability of the output. Complexity takes into account the size of the output rhythm tree, the arities of the tree nodes, and the number of grace notes in the final notation.\n\n### Compatibility \n\nOpenMusic 6.10 and higher.\n\n### Documentation\n\nSee [Project Wiki](https://github.com/openmusic-project/RQ/wiki)\n\n### Further reading\n\nThe RQ transcription system is described in:\n\n- Adrien Ycart, Florent Jacquemard, Jean Bresson, Slawek Staworko, [Une approche interactive pour la transcription rythmique dans OpenMusic](https://hal.inria.fr/hal-01298806), [JIM 2016](http://jim2016.gmea.net).\n- Adrien Ycart, Florent Jacquemard, Jean Bresson, Slawek Staworko, [A Supervised Approach for Rhythm Transcription based on Tree Series Enumeration](https://hal.inria.fr/hal-01315689), [ICMC 2016](http://www.icmc2016.com).\n\nMore in-depth description of the algorithm can be found in:\n- Adrien Ycart, [Quantification rythmique dans OpenMusic](https://hal.inria.fr/hal-01202257), Master thesis, IRCAM.\n\nSee also a [presentation of the library](https://medias.ircam.fr/embed/media/xac88c6) (in French).\n\n\nThe algorithm is based on the algorithms described in: \n - L.
