Downloading the Exploration Simulations

The book contains over 40 simulations, which can be downloaded here for free. The downloads include the simulator program, leabra++, which is part of the The PDP++ Software. Most major platforms are supported. Click on the appropriate link below to download the simulations for the associated platform. Most of these files are roughly 14Mb, so they will take a while to download over a slow link.

Next read this README file on how to install the program after you've downloaded it.

For configuring multiple users on a unix system (e.g., for teaching), see README.multiusers and multiusers_scripts.tar.

Updates and Version Numbers

Current version: 1.31 (most platforms)

We will be regularly fixing any bugs that are encountered in the simulations or the simulation software. Therefore, you should check back regularly to this site to see if there have been any updates, especially if you notice any problems. The changes and associated version numbers will be added to the following list (version numbers appear in the downloaded file name, e.g., sims_1.10_LINUX.tar.gz is the 1.10 version of the simulations for LINUX). If you find a bug that has not been fixed with a new version, please email the details (enough to reliably reproduce the bug) to anti-spam email addr img
