Jar archives are also extractable with 7-zip and other common compression utility.
You can edit and easily run the package within an integrated development environment such as or , under various platforms. Both are free and open-source.
2-letters problems have ab as their alphabet. 3-letters problems have abc as their alphabet... and so on.
If you don't want to fix it in your program you can ask for the alphabet at
http://labh-curien.univ-st-etienne.fr/zulu/oracle.php?problem=PROBLEM-KEY&alphabet=1 where PROBLEM-KEY is the 8-digit number that you can find here (you need to be logged in).
Ask for a string
You obtain there "Yes" if the string belongs to the automaton, or "No" if it doesn't. If the limit is reached the response is "Limit" (ie if you have used up your credit!).
Example: If you want to know if "0110101" belong to toy task 1 (key 00000001) :
Get the 1800 strings to classify
At this time you can't ask more membership queries (the target is "locked").
Example: If you want to obtain the words to classify for toy task 1 (key 00000001) :
Please note that this toy task have fewer words to classify than regular tasks.
Get the membership queries amount limit
Please count yourself how many query you have used if you need this information.
Example: If you want the query amount limit for toy task 1 (key 00000001) :
Please note that toy tasks have no limit.
Submit your classification
You can use wget in order to obtain the answers of membership queries and the 1800 strings.
wget call exemple
wget -O responseFile http://labh-curien.univ-st-etienne.fr/zulu/oracle.php\?problem\=01\&word=0110101
Troubleshooting: if you use a Proxy
You should be concerned by the following only if your environment is not correctly configured.
Command Line JVM Settings
The proxy settings are given to the JVM via command line arguments:
$ java -Dhttp.proxyHost=proxyhostURL
Setting System Properties in Code
Add the following lines in your Java code so that JVM uses the proxy to make HTTP calls. This would, of course, require you to recompile your Java source. (The other methods do not require any recompilation.):
PERL interface for Zulu
It provides a majority vote program written in PERL in order to provide an example of the use of the Zulu functions with a script language.
The 5 functions provided :
makes a membership query
returns how many queries are allowed
returns the symbols allowed for the target
asks for the test set. No zuluMQ calls are allowed since therefore.
sends your answers for the test set classification.
