River is the easiest street to solve via simulation or otherwise. Any unknown information adds a lot more work for the sim and preflop is where the least amount of information is known.
Does not work like that with AI.
If you use AI you have to know what kind of hand ranges it is going to arrive to the river with. But you don't know that if you do not have the "solution" (or should I say approximation) to how it is going to play earlier streets.
When Libratus was learning poker, it started the learning process from preflop play. If it would have started it from the river, then it would have not lead to any kind of solution.
You are right in that if we plug in river ranges, we can solve the game (actual solution within those ranges) without trying to solve preflop first given that our assumptions about those ranges that players arrive to the river with holds true. However, if players play earlier streets differently and arrive to the river with different ranges than we are going to assume, then we do absolutely nothing with that solution.
