Regarding FDG_inf: To my understanding it is basically a better version of FDG. I think there is only one FDG table which is what is used for light transport simulation. Actually calculating FDG_inf seems to be expensive since the Author mentions stochastic evaluation. So I presume that the table is filled with FDG_inf where needed and normal FDG otherwise.

I decided to implement the simplest version first, ignoring weights and spectral data. The source code of my attempt can be found in this gist. It is supposed to be a direct translation of the AnalogDecompositionTracking() function from the paper.

My test case is an achromatic, homogenous volume which I have artificially divided in control component and residual component, so that both together add up to the total collision coefficients. My decomposition tracking implementation fails with this simple setup.

Intuitively I thought I could simply run two delta tracking functions, one for the control component and one for the residual component and in combination this would lead to the correct result, as with calculating transmission. This also did not work.

Can you see where things go wrong?

The new pic also shows smooth shading which wasn't implemented for BDPT when I made the first version of that pic.
