We are interested in learning and contribute with any potential improvement of algorithms for relax and vc-relax available as options in &CONTROL calculation of pw.x:</pre><pre style="white-space:pre-wrap;color:rgb(0,0,0)"><a href="https://www.quantum-espresso.org/Doc/INPUT_PW.html#idm29" target="_blank">https://www.quantum-espresso.org/Doc/INPUT_PW.html#idm29</a></pre><pre style="white-space:pre-wrap;color:rgb(0,0,0)">We would like to know in which language the source code for relax and vc-relax is written. Any documentation concerning the implementation of these options might be helpful as well. </pre><pre style="white-space:pre-wrap;color:rgb(0,0,0)">Sincerely,
