3.1 OEAdaptor

class OEOpt::OEAdaptor

OEAdaptor is a base class which defines the interface for classes which adapt or transform variables and gradients during an optimization. Adaptors are useful in cases where function evaluations are performed in a different coordinate system than the variables being optimized (i.e. optimize polar coordinates but evaluate Cartesian coordinates).

3.1.1 AdaptVar

virtual bool AdaptVar(double *adaptedVar,const double *optVar)

The AdaptVar method takes a set of variables as the second argument and copies a set of transformed variables into the first argument. This method is commonly used to transform optimized variables back into the coordinate system of the original reference variables.

3.1.2 ClearPredicates

virtual void ClearPredicates()

The ClearPredicates method deletes all stored predicates set previously using one of the overloaded Set methods. Predicates control function initialization behavior of overridden OEAdaptor::Setup methods.

3.1.3 GetVar

virtual const double *GetVar(const double *refVar)

The GetVar method takes reference variables as an argument, and transforms them into the variable type or coordinate system that will be used during an optimization. Reference variables normally use the same coordinate system as the function evaluations that will be performed in an optimization. Many adaptors take Cartesian coordinates as the argument to the method, and return an array of variables containing the initial adapted state, such as torsion angles or a quaternion.
