For combinatorial optimization, there is now NVIDIA cuOpt, which is ridiculously fast: https://developer.nvidia.com/cuopt-logistics-optimization

Ceres can use GPUs for some solver bits too, I believe.

I didn't know that, thank you. Is there any information about the internals of this? Like the kind of solver etc?

Sorry but this is not optimization, this is a bunch of heuristics ran on a gpu.

That's how you solve combinatorial optimization problems. With a bunch on heuristics.

To be pedantic, it's one way to solve combinatorial optimization problems :)

What's your definition of optimization?
