For information on how to cite XtalOpt in your own publications, please see the "How To Cite?" section below.

As a free software published under the "NEW" BSD license, we do not require co-authorship as a contractual obligation, nor do we request it. As the XtalOpt authors have not characterized or studied the chemical system in your application paper, we would consider such attribution unnecessary, perhaps even dishonest. A simple citation of the relevant articles is sufficient for most cases.

Moreover, XtalOpt's open-source license was chosen to encourage open collaboration and to lower the barrier to researchers interested in developing new predictive techniques. We welcome contributions and encourage independent method improvement. If significant effort has been made by the XtalOpt authors to assist in implementing your technique, we may request co-authorship. However, scholarly articles describing independent modifications to, improvements to, or characterization of the XtalOpt code may follow the same citation guidelines as an application paper.

How To Cite?

If you use XtalOpt for the prediction of a new structure, please cite the implementation paper and the latest version announcement, i.e.,

  1. David C. Lonie, Eva Zurek, XtalOpt: An Open-Source Evolutionary Algorithm for Crystal Structure Prediction, Computer Physics Communications 182 (2011) pp. 372-387 DOI:10.1016/j.cpc.2010.07.048

  2. Samad Hajinazar, Eva Zurek, XtalOpt version 13: Multi-Objective Evolutionary Search for Novel Functional Materials, arXiv:2405.02138 (2024) webpage [preprint]

We also ask that you cite the RandSpg manuscript, if you employ this method for creating new random structures, and the XtalComp manuscript if you use this method for comparing the structures in your work.
