Hi Steven I decided to change the benchmarks. I have designed a new compact benchmark, with an execution time of aprox 3 min. The results are clear and compact and permit an easy evaluation. In the attached file you can see the result on my machine About the licenses. I Included in the benchmark program in the initial documentation the next paragraphs /// This program use for comparison only purposes the TimSort /// implementation, https://github.com/gfx/cpp-TimSort which license is /// https://github.com/gfx/cpp-TimSort/blob/master/LICENSE /// This program use for comparison purposes, the Threading Building /// Blocks which license is the GNU General Public License, version 2 /// as published by the Free Software Foundation. Now I am very busy with the exams of my students , but I am working a shot time every day in the correction of the documentation and in the final version before the validation. I hope to have ready soon and begin with the next process
