使用AI中的 Search Algorithm ，解决3-Snails Isolation问题。
3 Snails Isolation
This assignment will cover some of the concepts discussed in the Adversarial
Search lectures. You will be implementing game playing agents for a variant of
the game Isolation.
We are also implementing this through Jupyter Notebook, so you all may find it
useful to spend some time getting familiar with this software. During the
first week of classes, there was an assignment that spends some time going
through Python and Jupyter. If you are unfamiliar with either Python or
Jupyter, please go through that assignment first!

Git repository
Pull this repository to your local machine:
Setup
Activate the environment:
conda activate ai_env
—|—
In case you used a different environment name, to list of all environments you
have on your machine you can run conda env list .
Jupyter
Further instructions are provided in the notebook.ipynb . Run:
jupyter notebook
—|—
Once started you can access http://localhost:8888
in your browser.
Jupyter Tips
Hopefully, Assignment 0 got you pretty comfortable with Jupyter or at the very
least addressed the major things that you may run into during this project.
That said, Jupyter can take some getting used to, so here is a compilation of
some things to watch out for specifically when it comes to Jupyter in a sort-
of FAQs-like style
1. My Jupyter notebook does not seem to be starting up or my kernel is not
starting correctly.
Ans: This probably has to do with activating virtual environments. If you
followed the setup instructions exactly, then you should activate your conda
environment using conda activate <environment_name> from the Anaconda
Prompt and start Jupyter Notebook from there.
2. I was running cell xxx when I opened up my notebook again and something
or the other seems to have broken.
Ans: This is one thing that is very different between IDEs like PyCharm and
Jupyter Notebook. In Jupyter, every time you open a notebook, you should run
all the cells that a cell depends on before running that cell. This goes for
cells that are out of order too (if cell 5 depends on values set in cell 4 and
6, you need to run 4 and 6 before 5). Using the “Run All” command and its
variants (found in the “Cell” dropdown menu above) should help you when you’re
in a situation like this.
3. The value of a variable in one of my cells is not what I expected it to
be? What could have happened?
Ans: You may have run a cell that modifies that variable too many times. Look
at the “counter” example in assignment 0. First, try running counter = 0
and then counter += 1 . This way, when you print counter, you get counter
= 1, right? Now try running counter += 1 again, and now when you try to
print the variable, you see a value of 2. This is similar to the issue from
Question 2. The order in which you run the cells does affect the entire
program, so be careful.
IDE
In case you are willing to use IDE (e.g. Pycharm) to implement your assignment
in .py file. Please run:
python helpers/notebook2script.py submission
—|—
You will get autogenerated submission/submission.py file where you can
write your code. However, make sure you have gone through the instructions in
the notebook.ipynb at least once.
