@screwtape @rwxrwxrwx That depends on how you use it. MPI is simply message queing and passing. It allows you do do what you've been talking about, but without the shared kernel. Each node is doing it's own thing (which hopefully is synchronized algorithmically), but not always or even necessarily.My experiments were about using flocking algorithms as usually presented, but using mpi to pass messages between the nodes for things that may perturb or be perturbed by the natural flow of the algorithm.For example, one is running out of power. The others now know, and don't rely on it for say, video streaming. It can chill at the tail and do more basic things. Or a need for a specific sensor that only one or some of the nodes/agents/drones have on board, which may require one of them to position themselves at the lead or the tail... etc. There's a lot of things there.One "mission" I had was a swarm that carried explosives on each device, and had various recon/telemetry split amongst them. They would find their way to the target, and go simultaneously kamikaze. Failing the mission, they would return to base, or receive new targeting information. All while running recon to help further incursion. Blowing one or some of them out of the sky would not doom the mission.That's a bit harsh lol, but my first thoughts for this were entirely military. I somehow didn't manage to hear about Sandewall, so I look forward to Tuesday when I'll have some time to look at the resources in the repo.

@screwtape Cool! Glad to see you inspired by Vehicles.The question as to whether it is a game - it is in the same way that Conway's Game of Life is a game. Automatons are technically games.

@screwtape @vnikolov You're actually touching on subjects covered in Vehicles. Hopefully after your game, you'll have time to finish the book. Every chapter adds a new "bit" that progresses the concept.Although he's using the term "synthetic psychology," he's creating what otherwise would be called Artificial Life, but focusing on the psychological-appearing behaviours. It's all about the emergent behaviours, and not the ones you purposely programmed in.

@screwtape @vnikolov I just sorta kinda spoiled the plot. The idea is that after enough differing sensors and thresholds, their behaviour becomes less and less predictable, and things start to spontaneously emerge.That emergence is what you want. You've not scratched that part of the surface yet.It is exactly why GoL is so interesting, even from a scientific and mathematical point of view. None of those periodic sets (like the glider, etc) are programmed in. They emerge from the different (competing) rules.

@screwtape @vnikolov Also, flocking is, in itself, an emergent property. If you read the rule sets, you'll notice that they are extremely simple, and on their own don't say anything about flying in V shapes, etc. But they happen, due to the emergent properties.You'll get that from Vehicles if you follow through. Otherwise, you know how to build a base vehicle, but not how to allow emergent properties to come about.

@screwtape @vnikolov Besides, if you won a Nobel, you probably would be too busy shopping or travelling or something with all that money to get a lisp game finished.

@stux He is too stupid to realize how many kinds of doctors there are out there. Medical is just one of many.

@stux He is too stupid to realize how many kinds of doctors there are out there. Medical is just one of many. And even in medical doctors, there are specialists - something obvious to anybody who isn't a halfwit, or just trying to be cynical without realizing it makes them look like a halfwit.

It's sad that the leaders of the world are talking about how successful G7 meeting will be as long as Trump stays in his own lane, or everyone just ignores his crazy outbursts. USA had the world's respect, once upon a time.#trump #g7 #Canada #usa https://www.cbc.ca/news/canada/calgary/trump-crazy-outbursts-chretien-1.7559643

@hn50 Every once in a while I drop in to try out the newest release of Mezzano. It's not a very fast project at all, but each major release does have huge improvements.

@xkcd If the snake's tail was extended around the corner "downward" would that not add another step that is not adjacent to any other?

@praetor I wonder if Trump's Truth site is hosted on a VAX, and that's why so many of his posts LOOK LIKE THIS.

@nixCraft Isn't that another way of saying the US will do anything to keep propping it up, no matter the cost?This is a race that is China's for the taking. USA will let that happen?Huge sacrifices are about to be made to keep up the illusion as long as possible.Pay no attention to the man behind the curtain (or the one at the Whitehouse lectern.)
