Hi, @areeq-hasan! You can choose any of those two types of random walks to implement. I started implementing the unbiased random walk and got stuck with the [`WalkingNeighbors`](https://docs.rs/petgraph/0.4.13/petgraph/graph/struct.WalkNeighbors.html) part of...

I will work on the heavy hex generator.

I would like to work on the `cartesian_product` of graphs. If anyone is already working on it, please let me know.

Since that are a lot of graph operations that could be implemented, I think it is useful to have a summary of which operations are already implemented. Let me know...

Hi! I would like to solve this issue. Is checking the kwarg from the decorator in a list with all arguments that are accepted to the function and if it...

I see that the `gradient_kwargs` are arguments for the `diff_method`, so knowing the `diff_method` we could know which `gradient_kwargs` are accepted. Do you think that this is correct?

> Another approach could be to raise an error in the gradient transform if it gets a `kwarg` it doesn't understand --- that way an unknown keyword argument in the...

I have noticed that on `pennylane.interfaces.execution.cache_execute`: https://github.com/PennyLaneAI/pennylane/blob/1e3a73107d1a897ba04910492c1c698d41e8787e/pennylane/interfaces/execution.py#L126-L128 The `gradient_kwargs` variable when running the default interface (which I think is `autograd`) is modified to an empty dict because of the `pennylane.interfaces.autograd._execute`...
