[Insight-users] evolutionary optimizer...can't figure it out

[Dennis Nikitenko]

Folks,

I'm trying to use OnePlusOneEvolutionaryOptimizer for MI-based registration.
However, I can't get it to compile. My code looks like this:

..

typedef itk::OnePlusOneEvolutionaryOptimizer  OptimizerType;
typedef itk::Statistics::NormalVariateGenerator NormalGeneratorType;
typedef NormalGeneratorType::Pointer         NormalGeneratorPointer;

..

OptimizerType::Pointer      optimizer     = OptimizerType::New();
NormalGeneratorType::Pointer      generator     = NormalGeneratorType::New();

..

I haven't been able to find any examples on the Net, so I don't know what I'm
doing wrong. Here's the error message:
******************************************************************
