+=== Lab 2: Comparing Agent Programs ===
 In this lab session we will finish [[public:t-622-arti-11-1:lab_1_materials|lab 1]] and write a new kind of agent program mantaining a state.
-  - **Getting Started**:\\ Start by getting the file {{:public:t-622-arti-11-1:agents2.zip|agents2.zip}} and unzipping it into your working directory. This is largely the same file as we had for the last lab session, except some fixes to accommodate stateful agents, and code to run experiments.

This is largely the same file as we had for the last lab session, except some fixes to accommodate agents having a state, and code to run experiments.
     - In order to run the experiments later, you can use both functions: **random-agent-program** and **random-agent-measure** from lab 1 (that means you can copy them in the new file **agents2.lisp** =));
     - You only have to change the **random-agent-program** declaration in order to accommodate a small change in the way the function is called during experiments.<code lisp>

-  - **Comparing different agents**:\\ Try different agents (e.g. stateless random walk) and different performance measures. Does the stateful agent behave better than the others with any particular performance measure? You can add print commands to the experiment functions to get more information about the agents behaviour if you like.

-  - **Extra** If you finish the stateful agent and running the experiments, try creating an agent that moves through the environment in some orderly pattern. Make sure it visits all squares and cleans the dirty ones. Is the orderly agent more efficient than the random one?
