log4j is complaining

[Peter Drake]

I ran the MathProblem example. This was printed to the console:

Formula to discover: X^4 + X^3 + X^2 - X
0) 1.3086557   5.5780315
1) 0.6677475   0.27469397

19) 0.99180746   1.9351282
log4j:WARN No appenders could be found for logger  
(org.jgap.gp.impl.GPGenotype).
log4j:WARN Please initialize the log4j system properly.

After running for a few minutes, the program terminated. It produced  
a mathproblem_best.png image, but it never actually showed me the  
best solution -- presumably because it tried to "log" the solution,  
and the logger isn't working properly.

What should I do?

Peter,

Please be sure that the log4j.properties file is in the root directory of
your application. When you start the math problem via the file
"start_gp_mathproblem.bat" this is the case.
