I am pretty sure this is not AI in the sense of what passes for AI in the last 3 years.
“The algorithm” here is probably not more than a meduim complexity excel sheet, only running in real time and not on Excel.
Before this generative AI that is now the hype, there was already AI, it's an umbrella term. Under it you have machine learning.
In ML you have models like, machine learning regression models. These take in a lot of parameters and then do a prediction of a value. This does not cost a lot of computation and is deterministic so this could be used. This makes most sense for the engines.
There are also a bit more of advanced ML models with deep learning, like Recurrent Neural Network (RNN) or Convolution Neural Network (CNN), depending on the complexity of the models these can also be used but require much more computation (still possible on embedded hardware, but heavier than the regression models). These are used to find hidden patterns, do classifications, image recognition and such. So depending on how sophisticated the need is this could also be used, but I dont think so.
