So I've recently watched the Netflix adaptation of The Three-Body Problem. One of the central plots of the show (and from what I can gather, also the book series) seems to be disappointingly half-baked, especially considering that the plot device is the namesake of the show and the title of the first book.
Something that's established early on is that the San-Ti (or the Trisolarans) live in a chaotic three-body (really a four-body) system that can't be predicted, and despite having the capability to enter into lungfish-like dormancy their civilisations kept being wiped out due to not being able to predict when destructive climatic shifts would occur. You could, however, probably predict the chaotic orbits of three bodies solely through simulation, the aliens would probably be capable of this. The issue for us and why it is "unsolvable" is that there’s no simple one size fits all solution where you can plug in initial starting conditions and predict the state of three bodies at any point in time - but you can move each ball a little bit as a small amount of time passes, and then recalculate.
Of course, methods which iteratively compute position can and do deviate from reality, a small error can result in large deviations in the model over a very long period of time, but you can minimise error to a very high degree. And if you’re living on the planets themselves, you can constantly update the state of your simulation every time your model observably deviates from reality. So an iteratively computed model, continuously updated to align with current state, would probably help them avoid dying off at any given point, because T = 0 keeps being reset and you only ever need to calculate T + 1.
Note also, these are aliens that can unfold a photon’s higher dimensions, inscribe a supercomputer onto it, fold it back down, send it to a target site then communicate instantaneously with it via quantum entanglement. Aliens capable of incomprehensible space magic aren't capable of simulation, apparently.
Pretty sure they did that, ages ago, and moved on to more elaborate simulations. By the time they’re doing photon bullshit, they clearly have enough delta-V to leave their local volume.
I don’t think the 3body game was farming out intellectual labor. They were using it more like one of those plays about the life of Jesus.
