Hi,
Dear Sebastian,
I've installed the NumericalMethods package and I am trying to use the class DhbMultiVariableGeneralOptimizer to optimize a function. If I run the code of the test it works perfectly
| fBlock finder result | fBlock := [ :x | |r| r := x * x. r = 0 ifTrue: [ 1] ifFalse: [ r sqrt sin / r] ]. finder := DhbMultiVariableGeneralOptimizer maximizingFunction: fBlock. finder desiredPrecision: 0.01. finder origin: #(0.2 0.2 0.2) asVector; range: #(1 1 1) asVector. result := finder evaluate.
however, if I want to set my own function, (for example the sum of the elements of the parameter. fBlock := [ :x | x sum ]) it is throwing an error of ScriptOutOfBounds
I am not sure If I am doing something wrong or there is a bug in the implementation.
I haven't found too much documentation about how to use this package.
Is there someone using this particular class?
You can some information about the classes in Didier Besset book available here:

This package is part of the SciSmalltalk distribution: https://github.com/SergeStinckwich/SciSmalltalk Please feel free to join the mailing-list here: https://groups.google.com/forum/#!forum/scismalltalk
I don't have time to look at your problem at the moment. If you find an explanation or a bug fix, please tell us about this.
