Steps of the direct subspace algorithm.

StepAction

1Setting grid density for the free parameter(s)
2Mapping one measurement to parameter space
3Using the measurements, calculate LLR over the grid of free parameter(s)
4Repeat steps 2 and 3 for all measurements in the data set
5Forward the finest result in the local optimization routine
