You need to get some friends. I have a 27 line solution for this one and boy would I like a hint on how to cut 9 lines from it.

Is there any requirement for "leave no trace" other than having your exas terminate and not modifying files or leaving new files outside your host? I started playing through this and I got to the "Xtreme League Baseball" level and I am producing the correct output file (since the box for "create the specified file in your host" is checked), all my exas terminate, and I haven't written to any other files, but for some reason it doesn't think that I have left no trace.

Do you actually complete all other objectives? IIRC it's a prerequisite to leaving no traces.

Edit: The only other thing I can think is that I'm somehow modifying a file accidentally but I shouldn't have any instructions that modify any files other than the new file I create. Here's my code: XA: receives calculated result and player name; keeps track of current maximum score and writes the name of the corresponding player to a new file code:

Can't really tell you what's wrong in regards to trace because the program you posted above doesn't even complete, it hangs on cycle ~27 when all three exas wait for a COPY M T instruction at the same time. edit: maybe one of your exas was manually set to local mode before runtime? edit2: yeah on all-global XA catches the name from XC which messes up the flow. The program at least executes if i start XB and XC in local mode, but the first sim never completes because your program fetches the wrong name.

Oh yeah i know what your problem is: T permanence. You think you can save both the previous received number in T and the current number in X and compare them against each other, but that only works once, since your previous value gets overwritten once you compare them. Which means you always test the current value against 1, here:code:

Well I accidentally wrote a sort algorithm with 2 EXAs I didn't even need for one of the puzzles, Digital Library Project, to make sure they go in the right order (though I think I will need it for a lowest-possible-activity solution?). I really don't know how some of the cycle solutions are even possible, mind. (Say, the 4th tutorial in about 100 cycles, i can't figure out any way to make a loop run that fast!) This game is so goddamn fun though. Oh, and the hacker battles are delicious. Olpainless fucked around with this message at 14:39 on Sep 26, 2018 |

Well I've finished the main campaign now - I'm still utterly mystified as to some of the cycle counts on some of these (EG: sub 300 for Exa Blaster 3, HOW? The file length changes each time so you can't realistically unroll loops afaik, and just sending that data across 8 times is more than 300 cycles) Final mission is really enjoyable, US Government is probably the hardest mission in the game to suss out, Unknown Network 2 is a breath of fresh air in the final sprint.

Sax Solo posted:How fast can you make eight copies of a file? If it's variable length? Approx 3 cycles per string, plus the initialisation and finalising cycle cost. It doesn't seem amicable to just a bunch of Copy F M commands because of the variable length. Edit: I've got it down to 365 by padding the file to be at least 12 characters, just copying 12 across, and then later removing numeric values, but I'm struggling to see where else I can save on this. Can gif/code on request. Double edit: Even on this I think I can improve, I've got some stuff going on I don't think I need to. Triple edit: 350 on this approach. (Then 326 with an improvement to the sync loop) Fourth edit: 272! Partially unrolled the write to data loop, the first 9 characters you can just stream - 25 I GET THIS NOW EDIT: Ahahahahaha 244 and better than top percentile (you only need to copy the file 7 times) Olpainless fucked around with this message at 16:28 on Oct 24, 2018 |

I'm on the satellite mission, trying to encrypt a signal. I have to take two numbers, add them together and output them, and if the number is bigger than 9999, roll over to 0. But I can't store any number larger than 9999, so I can't modulo 10000 as I'd want to do. Right now the only way I can think of doing this is summing the values, checking if the result is 9999, stepping back and subtracting 5000 from both values and then doing the sum again. Probably having then to double check the value isn't -1 if the two original values summed to exactly 9999 in the event a later test run throws that at me. OR, swizzle the values, sum the digits individually, and then truncate any oversized values before concatenating them back together I know that will work but it feels like such a godawful kludge for just doing MODI 10k that I feel like there must be a simple way to do this I'm missing.

My method, which IMO is slightly better: Take value A which is in range [0, 9999], subtract 9999, and the new value is now in the range [-9999, 0]. Add value B. This will never overflow. If the result is 0 or below, add 9999, otherwise subtract 1. You now have A + B mod 10000.

Can someone tell me how to gracefully check when an Exa is done writing to a file so I can have the Exa doing the reading stop and move on? For the first modem mission I have the writer copy a value to M when it's done and have the reader TEST MRD at the beginning of its loop so when that becomes true it copies M to X in order to allow the writer to die. The last step is necessary because TEST MRD on its own doesn't clear M. I feel like there's got to be a better way! Here's code I'm not proud of that gets the job done: XA code:

There are a bunch of different ways you can do it. - have one exa that loops forever, that is then KILLed by the other exa when the job is done - have one exa count how many iterations are needed first, and send that to the other exa so that it can use a counted loop - have one exa tell the other exa after every iteration whether it's done yet (e.g. send 0 when done, or 1 if it needs to keep going) Usually the first one is the most "elegant" in terms of cycles and code size, but it's bad for your activity score. Sometimes you can do a clever trick, for example if you're copying numbers into a file, instead of COPY M F you can use ADDI M 0 F, and then the sending exa can write a string instead of a number to "kill" the receiver without actually using a KILL command.

Thanks! I might try to rewrite it to implement your 3rd option since I'm already half doing it. I really don't like TEST MRD because it forces me to use NOOPs to wait for the other Exa's loop to cycle around and that displeases me. Edit: Or I could have the writer TEST EOF, kill the reader, restart the loop, and become the next reader... Tiny Timbs fucked around with this message at 04:07 on Jan 8, 2019 |

Hello, all. Picked up this game in late December, have been slowly playing through it. I'm on the post-epilogue tasks now, and wow are some of these are really twisting my brain! I've got 5 of 8 done so far, and a couple of those are real slop, hitting the 150 command limit exactly or running into the 10,000s of cycles. My Steam-ID is Bobulus, if anyone is still playing and wants to add me. https://steamcommunity.com/id/bobulus Right now, I'm on the airport one, and I thought I had a fairly elegant solution mapped out, but it required each repl clone creating a file, dropping it, and then picking it back up and unfortunately that broke my code, because I forgot about the file number increment. D'oh! I'll probably have to fix it by never actually dropping the file, and making a new replicate EXA to do the job instead. Bobulus fucked around with this message at 23:19 on Jan 24, 2019 |

Someone is not a good programmer just because they get on top of the Exapunks scoreboards. Rather the contrary, if the hacks required for size/speed domination was used in a real programming job, your code reviewer would murder you with a rusty spoon. Collorary to this is that being on the bottom of the scoreboards does not make you a bad programmer.
