The code here is the as that which appears in the following locations:

• http://www.cs.berkeley.edu/~russell/code/code.tar.gz
• http://aima.cs.berkeley.edu/lisp/code.tar.gz

More information about this code is available here:

The changes made are discussed in the file ChangeLog in this directory.

Setup

Download the code and then start up SBCL:

$ git clone git@github.com:oubiwann/cl-aima.git
$ cd cl-aima
$ sbcl

Load the code, compile it, and run the tests:

* (load "aima.lisp")
...
T
* (aima-load 'all)
...
T
* (aima-compile)
...
T
* (test 'all)
...

Usage

At this point, you're ready to use the code that has been defined in the various .lisp files. Looking at the tests may be helpful, for instance, take a look at the test file agents/test-agents.lisp.

In it, you will see an example for having an agent run in the "Wumpus world" environment. You can call that directly:

* (run-environment (make-wumpus-world :max-steps 30))

For this exanple, you will see a series of Wumpus screens like so:

...
At Time step 6:
Agent [1 = -10006] perceives (NIL BREEZE NIL NIL NIL)
      and does (TURN LEFT)
