The differential evolution algorithm is a robust optimization method which avoids local minima but at same is a highly effective. GenX is written in python and uses the wxpython package for the Graphical User Interface (GUI) Screenshot. A model to fit is defined either through a GUI plug-in or via a python script. The possibility to script everything makes it easy to develop completely new fitting model. Clearly, GenX is extremely modular, making it possible to extend the program with models and plug-ins for most fitting problems. At the present GenX is shipped with models for x-ray and neutron specular reflectivity, off-specular x-ray reflectivity and surface x-ray diffraction. A detailed description, of a older version, has been published in . Feedback and Help: You can find a manual with examples at , for reflectometry a good start is with the SimpleReflectivity guide and our Tutorial Videos . Naturally a program does not become better if I do not get feedback from you! If you found a bug or want to have something included in the program submit a ticket on SourceForge at . ### Package name * genx --- ### License * GPL-3.0+ --- ### Last updated * 24 August 2026 - latest/stable * 18 September 2026 - latest/edge --- ### Websites * [aglavic.github.io](https://aglavic.github.io/genx/ "https://aglavic.github.io/genx/") * [sourceforge.net/projects/genx/](https://sourceforge.net/projects/genx/ "https://sourceforge.net/projects/genx/") --- ### Source code * [github.com/aglavic/genx](https://github.com/aglavic/genx "https://github.com/aglavic/genx") --- ### Report a bug * [github.com/aglavic/genx/issues](https://github.com/aglavic/genx/issues "https://github.com/aglavic/genx/issues") --- ##### Report a Snap Store violation * [Report this Snap](https://snapcraft.io/install/genx/rhel#report-snap-modal) --- ## Enable snaps on Red Hat Enterprise Linux and install genx Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd Snap is available for [Red Hat Enterprise Linux (RHEL) 8](https://www.redhat.com/en/enterprise-linux-8) and RHEL 7, from the 7.6 release onward. The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below. The EPEL repository can be added to **RHEL 9** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 8** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 7** with the following command: ``` sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ``` Adding the *optional* and *extras* repositories is also recommended: ``` sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" sudo yum update ``` Snap can now be installed as follows: ``` sudo yum install snapd ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` Either log out and back in again or restart your system to ensure snap’s paths are updated correctly. ### Install genx To install genx, simply use the following command: ``` sudo snap install genx ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
