About Elvira ...

The ELVIRA system is a tool to construct model based decision support systems. The models supported are based on probabilistic uncertainty. We are working to obtain our first stable version of Bayesian belief networks with discrete and continuous variables.

The ELVIRA system has an easy to use Graphic Interface User (GUI) which allows you to define models clicking your mouse. But, if you wan't use it, you can edit the ASCII format of the ELVIRA system to introduce your models.

ELVIRA has been programmed only with the JAVA language. So, you can use it on any operating system.
Current version support Bayesian  Networks and Influence Diagrams with discrete variables. It have methods to inference, learning, abduction and making decision. 

The link Download bayelvira2 allows you to obtain the source code of ELVIRA as a .tar.gz file. You can decompress it in Unix or Linux using:
tar zxvf bayelvira2.tar.gz

Previous file can also be decompressed in Windows 95, 98, 2000, XP using the Winzip program.

You can obtain the very last version of the source code using cvs software with the commands:

setenv CVSROOT
cvs login

Then, just press Enter when the password is required:

CVS password:

And finally use the next command to retrieve the files:

cvs checkout bayelvira2
