Thanks. Are there any links where I can learn more about this?

I did some Googling and it appears that there are some examples where people say combining multiple models or multiple runs of the same models leads to improvements: https://www.sciencedirect.com/science/article/abs/pii/S00104... https://arxiv.org/abs/2203.11171

But presumably people are less likely to publish a paper when an approach doesn’t work.
