I have been looking into tropical algebra/geometry for a research problem I'm working on in optimization. Tropical math gets referenced a lot in the literature, but it seems to me that its mostly just rephrasing equations with "max" or "min" constraints into a tropical algebraic equation and then saying hey look we can do this. I haven't found that many examples where the tropical framework actually provides a new solution or application, so I was wondering if anyone had examples?
Here are two papers that I think did this well:
https://arxiv.org/pdf/1904.01082.pdf In this paper the authors rephrase a problem into tropical math and use it to come up with an approach to a generalization of an existing problem, which is (in my opinion) a lot more natural in this setting. They use this insight to come up with a new algorithm to solve the problem, which has trade-offs with the existing algorithms.
https://arxiv.org/pdf/1805.07091.pdf I would say that this paper is in the camp of just rephrasing things into the tropical setting, but its about neural networks, where a major open problem is coming up with interpretations, so I would say that this counts.
