desdeo-frontend is a graphical user interface (GUI) for various interactive multiobjective optimization methods found in DESDEO. desdeo-frontend is related to the ecosystem of packages belonging to DESDEO. The GUI can be used to define, explore, and solve multiobjective optimization problems of varying type interactively. desdeo-frontend has been developed as a React application in TypeScript. desdeo-frontend is also an example on how the interactive visualizations implemented in desdeo-components may be used, and how the desdeo-webapi API can be utilized in practice.

Before installing desdeo-frontend, make sure a server with desdeo-webapi is first installed and running, either locally or on some remote machine. To run it locally, follow the instructions on desdeo-webapi's GitHub page.

From here on, it is assumed that a server is run locally with the address http://127.0.0.1:5000.

To install desdeo-frontend, make sure your system supports a Node.js environment and a dependency manager, such as npm or yarn is available. yarn is recommended as it has been tested to be working. From here on, it is assumed that yarn is available.

When Node.js is installed and a package manager is available, desdeo-frontend can be installed by running the following commans:

$> git clone [email protected]:gialmisi/desdeo-frontend.git
$> cd desdeo-frontend
$> yarn install 

To run the GUI application, first, make sure that the variable API_URL in src/App.tsx is set with a valid URL (e.g., http://127.0.0.1:5000). Then, run the start script by issuing the command:

$> yarn run start

This should launch the GUI application in a new tab in your web browser.

To use the GUI, a username and password are required. For locally running the GUI, a dummy user(s) with a password(s) can be set readily by utilzing the utilities provided in desdeo-webapi. After logging in, the navigation bar will update with menus to access various features of the GUI.

Currently, only a dummy problem can be defined through the interface. However, the intractive methods support solving problems with both analytical formualtions and/or discrete formulations. Problems must currently be added manually to the databse in desdeo-webapi. See its documentation for additiona details.

Currently interfaces for the following multiobjective optimization methods have been implemented:
