I understand very well what determinism means . . .
Oh, so then you know that the "dynamic" system is just as deterministic as any other system; that can be seen because the AI is determined by the situation and internal scripts. To talk of one AI being "determine" and another being "dynamic" are misnomers and add to the confusion.
Where you have the real difference is the factors which influence the AI's choice of actions. In EUII (for example) the AI's actions were influenced by their base situation (year, date, friends, enemies, sliders, etc), events, some historical in nature, some random, and internal, individualized country specific AIs.
In EUIII, the AI's intelligent reactions may be better, and are according to all reports. However, the last two factors, events, and internal, country specifi AI's are now missing. Both those factors are what gave EUII it's historical feel, something that is completely lacking in EUIII, again from all reports.
As you can see, none of that has the least bit to do with determinism. Both are utterely and completely determined by AI routines. The differences are those factors that are allowed to determine the AI's actions, not that one is determined and the other isn't.
