- computeUpdate
Compute the value of p given a new parameter state x and the region radius.
- getPredictedReduction
Returns the predicted reduction from the quadratic model.
reduction = m(0) - m(p) = -g(0)*p - 0.5*
- getStepLength
This function returns ||p||.This computation is done inside the update because
it can often be done
- initialize
Must call this function first. Specifies the number of parameters that are being
optimized.
- initializeUpdate
Initialize the parameter update. This is typically where all the expensive
computations take place U
