Commons Math - Problem with deprecated OptimizationException using NelderMead.optimize
Hi,
I am new to this forum and this is actually the first time that I use
Apache Commons Math.
I would like use NelderMead class (in optimization.direct package) for
minimizing the parameters of the function that I wrote (which
implements MultivariateRealFunction).
As you know, a call to optimize method in NelderMead should be caught
for three different exceptions, namely FunctionEvaluationException,
IllegalArgumentException and OptimizationException.
However the last one (OptimizationException) has been apparently
deprecated in version 2.2 (to be removed in 3.0). I am using the last
version of Appache.Commons.Math which is apparently 2.2. (although I
see a Javadoc CommonsMath 3.0 snapshot on the website which is
confusing, as there is no sourcecode/jar for version 3.0) and since I
am using Eclipse, I can clearly see that OptimizationException is
visibly deprecated. However (as expected) the compiler does not
complain about it and the program compiles and only at run time the
following exception is thrown:
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError:
org/apache/commons/math/optimization/OptimizationException
It seems that OptimizationException class cannot be found! Usually,
when a class is deprecated, it is still possible to use it (although
not recommended). Beside, I have no choice but to use it (call to
NelderMead.optimise requires to catch this exception). I greatly
appreciate if you can please provide me with your feedbacks.
Alternatively, I assume having the version 3.0 (if available) can
solve my problem as well.
Thank you,
Babak
----------------------------------
My code is simple and pretty straightforward as in the following:
NelderMead apacheNelderMead = new NelderMead();
MyMultivariateRealFunction minFunct = new MyMultivariateRealFunction();
double[] start = new double[48];
Arrays.fill(start, 0.1);
try {
minValue = apacheNelderMead.optimize(minFunct, GoalType.MINIMIZE, start);
}
catch ( FunctionEvaluationException e) {
System.out.println(e);
}
catch (IllegalArgumentException e) {
System.out.println(e);
}
catch (OptimizationException e) {
System.out.println(e);
}

commons-math-1.x and commons-math-2.y are not compatible...
Unfortunately, I don't know any solution to your problem.

My sincere apologies to you Gilles and other members of this forum.
Indeed, there was a problem with the ‘runtime’ classpath. Apparently,
in addition to adding the jar in the Java Build Path pane, Libraries
tab (invoked in the project properties in the Eclipse) [‘compile time
path’], one also has to add the jar in the Classpath tab of ‘Run
Configuration’, which I forgot to it! Sorry about this unnecessary
disturbance.
Although this resolves my initial problem, I still have a more serious
problem, but I am afraid it is out of the interest and scope of this
forum. The problem is that I am using NelderMead (example below) in
the Repast Simphony Elipse environment. The commons-math-1.1 is
already integrated and is a part of Repast Simphony Development
Libraries. So, it does not like the fact that I want to use (import)
commons-math-2.2!
NelderMead unfortunalty does not seem to be included in the
commons-math-1.1 and trying to fool Reapst by replacing
commons-math-2.2 with commons-math-1.1 (after changing its name to
commons-math-1.1) did not helped!
I am not expecting to have an answer about this specific case problem
here, although I will surely appreciate if someone has an idea.
In any case, sorry and thank you again.
Regards,
Babak

Re: Commons Math - Problem with deprecated OptimizationException

Posted by Babak <ba...@gmail.com>.
Hi Gilles,
Thank you for your reply. I added commons-math-2.2.jar (and even
commons-math-2.2-sources.jar) to the Java Build Path of the project in
Eclipse in the Libraries tab of the project (like I did for another
external jar that I use without occurring any problem). The fact that
the compilation is done properly and that there is no exception thrown
for previous classes or method calls (e.g. NelderMead, or even
FunctionEvaluationExcpetion and IllegalArgumentException) forced me to
believe that the problem is with deprecated OptimizationException. In
fact, in the example code, I changed the order of the catches so that
OptimizationException is not the last one to be thrown. However, the
run time exception error remains the same, that is,
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError:
org/apache/commons/math/optimization/OptimizationException
Many thanks,
Babak

Are you sure that your classpath is the same for compilation and execution?

It would help if you could provide a minimal but functional example, one
with which we can try to reproduce the problem.
