Software Praktikum Group 3

This is a project that we have worked on in a team of three during my Bachelor's degree (2018). The project was about building an AI to compete against other groups in a board game that is similar to Reversi (Othello), but with additional complicating rules and multiple players.

The tasks included building a framework that:

• can simulate the rules of the game
• can communicate with the server
• implements an aritificial intelligence logic to choose the moves

This AI is "traditional" in the sense that it uses a handcrafted evaluation function together with alpha-beta tree search to choose the next moves. Our resulting agent was able to beat and replace the annual course's all-time best AI, which was reigning for several years before that.

How to compile our Project

To compile our project simply go into the basedirectory and run:

1. ant

This implicitly runs:

1. ant clean
2. ant compile
3. ant deploy which clears previous .class files, compiles the project and creates an executable .jar file in the basedirectory.

Ant should use the buildfile built.xml by default

How to run our project

In the basedirectory call:

java -jar Phteven.jar -s serveraddress -p portnumber

where serveraddress is the address of the server and portnumber is the port number.

All Commandline Parameters:

This is a list of all commandline arguments:

shortname	longname	option	is mandatory	default value	description
-s	--server	STRING	yes		The server address you want to connect to
-p	--port	INT	yes		The serverport you want to connect to
-h	--help	FLAG	no		Prints a hopefully helping text
-l	--loglevel	INT	no	3	The maximum LogLevel that should be printed. 0:NONE 1:ERROR 2:WARNING 3:INFO 4:DETAIL 5:DEBUG
-o	--log-file	STRING	no	sysout	Specify an output FIle for Logging. Default is sysout.
	--log-performance	FLAG	no		Enables performance Logging. Logging the performance can have an Impact on the performance and will generate more output.
	--log-ext-perf	FLAG	no		Enables extended performance Logging, which offers more information.
	--disable-ab	FLAG	no		Disables Alpha-Beta-Pruning
	--disable-sort	FLAg	no		Disables move-sorting
	--disable-itDeep	FLAg	no		Disables iterative deepening
	--asp-window	INT	no	15	Set the aspiration Window size. 0 disables Aspiration Windows

Arguments with either a STRING or INT option require an additional option after them.

STRING can be anything.

INT has to be a number

Arguments with a FLAG option do not require an extra option.
