> On a sparse map, you can tune A* all day, but ultimately if your paths involve more than 1) vertices on the obstacles or 2) straight lines from src to (maybe some of) those vertices to goal, you have created suboptimal paths. You would

I feel this is not needed if you tie-break nodes in Open to favour lower h-values. This leads to a node selection bias for deeper paths, which are more likely closer to the goal. If you look at runs, this tie breaking makes A* behave like a

- Run A* on the optimistic pathfinding graph (no obstacles on the unknown cells). - Follow the path found (if there's none, that's it) - As you follow the path, sense the world and take note of new obstacles. - If there's an

A* searches on a generic weighted graph, there's no vertical, horizontal nor diagonal movements. The only thing that matters is which nodes exists and how they are connected. If diagonals on a 2D-grid are forbidden, then you need to us

I don't think it's just the carbs, but they likely don't help in today's society. We became too efficient at packing carbs in our diet and at the same time too sedentary. Beyond macro-nutrients, what I think the true rea

How can a duopoly produce regulation? That'd be straight out corruption unless someone came up with a new word for it that suddenly made that legal, moral, and efficient.

It can be a really cool thing too if both cultures open each other to exchange languages and celebrations, but it requires a lot of effort from everyone.

I think it hijacks the local culture, there's probably a better word, but I'm no native.

There's a certain amount of people that can adapt to a place, but if too many people of common culture comes in they just hijack the place. In Canada it seems to me they didn't establish the limit properly and people also worked a

Tree search is natural when you want a path to navigate, so it does fit a sequence of interactions in a conversation too. I agree that both, DFS and BFS are likely awful[^0], but a more informed approach can probably do better[^1]. Also, at

I feel humans like doing something in between, maybe a bit like A* would do sometimes.I wouldn't call it A* because of the lack of a consistent heuristic and also lack of strictly numeric evaluation, but it's an in-between DFS and

I guess it's long enough for poor maintenance to let salty water do its thing. AFAIK even cars sent across the Pacific show damage when they arrive and special care is put to coat them.

Cool! Is there historical data available? It'd be cool to have a slider to go back in time and maybe loop over the data over a specific range to show how it evolves. Also, what bounds this to Chile? It seems that using location coordin

I guess the only natural way would be to have operations send you back to the Base type, and then have a `TryInto(v: Base) -> Result<Refined>` function that would verify the predicate and allow you getting back into the refined typ

I made up the syntax to try to keep it easy to read for people using python/rust/c. I just realized my lambda syntax on the Nat predicate is redundant because I didn't clean up and that using snake_case for function names wou

Refinements embed a predicate that elements of the new type must pass. def Nat = Int: (|x| -> x >= 0) Dependent types allow types to be computed from functions (and depend on arguments, otherwise it seems they become just wei

Which to my straw man's understanding is also why cancer in young people is more likely to go out of control and seems to be more lethal than on older people.

I agree it can be useful (latency, availability, using off-peak resources), but running globally should be a default and people should opt-in into fine-grained control and responsibility. From outside it seems that either AWS picked the wro

Does it? I've seen outages around "Sorry, us-west_carolina-3 is down". AWS is particularly good at keeping you aware of their datacenters.

It may be a step forward in terms of gathering data and defining the filter, but pushing up this filter might be expensive unless there's enough volume to justify it. I took it as a comment on that generally models will be biased towar
