Project 7: Thread Based Soccer Server (worth 35 bonus points)

Assignment Day	November 30, 2009 (Monday - midnight)
Due Date	December 08, 2009 (Tuesday 5 PM, but no penalty until the start of December 09). You will need to set up a demo time for the project see schedule page on available days).

Collaboration Policy - Read Carefully

You must work on this project individually, but you may discuss this assignment with other students in the class and ask and provide help in useful ways, preferable over our email list so we can all benefit from your great ideas. You may consult any outside resources you including books, papers, web sites and people (but no penguins or sea urchins).

If you use resources other than the class materials, indicate what you used along with your answer.

Objective

Your job is to create a thread based soccer simulator (using p-threads) where competitor can create their own soccer teams and use your simulator to compete. If you are curious what such a simulator would look like take look at ASCII soccer which is a simple simulator implemented in C. Your implementation should provide the same functionality as ASCII soccer, but each soccer player needs to be implemented as a separate p-thread.

This is an old project from a previous years - that some enjoyed working on - a bit of warning - your server may initially a bit slow, so you should try strategies to make it work as efficiently as possible.

Questions/Answers:

• What is the environment like?
The world should be a grid based world -- were there are only specific locations that the players can inhabit.
• How far should the ball go?
• The direction should be a bit noisy -- i.e the ball may not go exactly away from each player
• The distance should be a bit noisy -- sometimes the ball goes further sometimes it goes shorter
• Can players be on top of another?
• This should be prohibited (this is also what ASCII soccer does).

Specifics:

In addition to develop a soccer simulator you will also need to implement two example teams:
• one team that uses a brute force technique such that each player goes directly towards the ball.
• one team that you design yourself.
You need to write your simulator and teams so that it can easily be distributed and used by other people. Here are some HINTS:
• Be careful how you define your team API
• Look at the README file provided in ASCII soccer for hints or an updated README file here: http://www.cs.uga.edu/~maria/classes/4730-Fall-2008/project3soccer/soccer/README

Other Information:

Make sure you environment sees the following executables:

/opt/sfw/bin/g++
/usr/ccs/bin/ranlib
/usr/ccs/bin/ar

How to get the ASCII soccer and run it on ATLAS:
• get the ASCII soccer software at: http://www.cs.uga.edu/~maria/classes/4730-Fall-2008/project3soccer/soccer.2.0.tar
• untar file:

  tar -xvf soccer.2.0.tar

• go to directory:

  cd soccer

• README file at: http://www.cs.uga.edu/~maria/classes/4730-Fall-2008/project3soccer/soccer/README
• see Quickstart in README file to run server and teams
