I think all this is premature optimization for me :) as I'm only building an early prototype (I'm doing a start of Dempster Shafer Theory [1] implementation (actually Transferable Belief Model)... and it's won't reach a big size for a while. It allows to have an imprecise, incomplete even uncertain value for a proposition (sort of multi-valued attribute with confidence...).
Waaah, belief and plausibility as sum over numbers; shudder; political-systems-failure through machine calculations; market-meltdown through machine calculations; poverty-for-everyone through machine calculations :( Anyways, have you compared to Pei Wang's NARS (or perhaps his "The limitation of Bayesianism"), that would be interesting [OT]. Tried to convince him that fractions are sufficient for him but he liked floats more (his early J* prototype had no system support for fractions ...).
Do you have calculations of your model's epsilon on which you base your "imprecise", "uncertain", etc ? Or do you at present (for the prototype) just stab in the dark.
I use it to get expert opinion on values, it's a known technique for different captor data fusion, but in my case, it doesn't demand too much performance as the combination is not that important (compared to sensor data fusion) ;)
