Java Sorting Programs

This is a dataset of 126 Java computer programs, all sorting an array of integers in ascending order. The programs have been gathered from the web in 2015 as part of the DFG funded project _Learning Feedback for Dynamic Tutoring Systems_ (FIT) with grant number HA 2719/6-1. It is meant as a benchmark dataset for methods working on clustering and/or classification of structured data (sequences, trees or graphs). For copyright reasons, we can not provide the source code directly. Instead, this dataset contains meta data about the data points as well as pre-calculated distance matrices.
