[Insight-developers] Amoeba optimizer,

[Luis Ibanez]

Hi,

I'm having trouble with the Amoeba optimizer.

vnl optimizers have been adapted by creating
an adaptor cost function like:


  +-------------------+
  | vnl_cost_function |
  +-------------------+
            ^
            |
+-----------------------------+
| vnlCostFunctionAdaptor      |   +--------------+
| has a CostFunction::Pointer |-->| CostFunction |
+-----------------------------+   +--------------+


Then, the pointer to vnlCostFunction is passed
to the specific vnl_optimizer.

It seems that Amoeba makes a copy of itself,
and assumes that with the cost_function has
no state associated with it.  So, it basically
creates brand new vnl_cost_function (only respecting
the type).  That causes that the real CostFunction
pointer is never passed to the real optimizer...


Any suggestions ...


Thanks


Luis
