  Go to the guy's site where Tomasz download his source code from, download his 
source code, and stare at that one instead, I think its a lot closer to what 
you want. http://www.bionik.tu-berlin.de/user/niko/cmaes_c.tar.gz

    Subject: [amibroker] Code help please... Optimize with CMAE


    Hello,

    I have been staring at the CMAE DLL stuff for days and I really need 
    some help to figure out how to use it in a particular way.

    I would like to use the optimizer in a generic sense to do the 
    following from AFL without using the internal backtester, meaning only 
    AFL in indicator mode:

    Initialize 2 items:
    item 1 is X and has a default,min,max,step,current,best values 
    1,1,1000,1,1,1
    item 2 is Y and has a default,min,max,step,current,best values 
    1,1,1000,1,1,1

    The objective is to optimize X and Y so that X*Y==100

    objective function in AFL:
    function Objective()
    {
    return 100 - X*Y;
    }

    The steps I would need to take as I understand them are:

    1. Initialize the X and Y OptimizeItems by calling 
    OptimizerInit( with bunch of arguments) --most arguments are 
    irrelevant to this test.

    2. Start the optimizer engine by calling pfEvaluateFunc( pContext ) -- 
    there really is no context that I understand for this test.

    3. The DLL calls back for the objective AFL function

    4. It runs step 3 a number of times to find the solution of X=Y=10

    5. OptimizerFinalize(same bunch of arguments as step 1)

    Of course I would prefer that step 3 is AFL calling the optimizer DLL 
    instead (simple mode), but I did not think that is how the CMAE works.

    Anyway, if I could get this simple case to work, I am sure I could 
    figure out how do do much more complicated cases after that on my own.

    Of course if there is no way to use the existing DLL without changing 
    it, I would like to know that also. I should be able to make modest 
    changes to the DLL myself.

    Please any hints or AFL code is appreciated.

    Best regards,
    Dennis
