    Let's say a specific problem expected to be NP turns out to be P, but with a ridulously high power, say N^100. How does that help? It still requires approximation methods that find local optimums, like genetic programming.

    True, thing is most of us agree that P is most likely not equal to NP Still, non deterministic polynomial algorithms for such problems can still be faster or slower compared to each other and there's a lot of work that goes into making them as fast as possible, usually in the form of SAT-solvers (a nice keyword for you to google more detail there)

Why are you people not vegan? That is how to almost eradicate cancer. That is how to end the worldwide obese epidemic. That is how to stop our species degenerating. That is how to save the planet and all the species on the planet. That is how we will evolve. I do not understand the complexities of mathematics. That is what you people excel at but could you people please go vegan and then direct your brilliant minds to building a vegan world.

    I would say "could be Mozart" would be less biased, because P=NP only implies that for every problem whose solution can be easily checked (NP), there is a method that can systematically resolve it (within only a polynomial number of step). But not that being able to check a solution would automatically imply discovering that method.

    You also as a programmer, have to give some thought as to how long an operation might take to be performed. If it often takes too long, then the user needs a progress thermometer, so that it does not appear that their computer software has just frozen or crashed for no apparent reason, then they start doing drastic things that could cause problems, such as force-quitting. Also, any data file updates should be done in such a way, that if the program becomes interrupted, the data is quite unlikely to become corrupted. Thus, perhaps the old state of the files is maintained as the current version, completely until all updates have been completed. Thus, the worst-case scenarios is simply starting the process over again, and not catastrophic data loss. BTW, I notice that some progress thermometers, initially have no idea how long the process will take. Rather, they self-calibrate and will estimate how long, based upon the rate that it is progressing so far after a short wait going into doing the process.

    5 жыл бұрын

    @@deoxal7947 The calculation is quite complex, due to factors beyond the computer's control. For example, the hard drive or even USB flash drive has its own computer controlling it. You can't tell it to hurry, it takes as long as it takes. The computer doesn't even know how long it takes, unless it can find that data in the device driver or in some database, other than by testing or bench-marking it. Some devices are faster, some are slower. Or if downloading, the speed of the internet and wifi links, affects it, and maybe the server is running slow today. When progress bars start without an estimate and take several seconds or more to estimate, that is because the computer is trying to get a small test percentage done, and it times the progress against its own internal clock, and then extrapolates "At the current data flow rate, 2 minutes are remaining." If then it becomes 3 minutes and 5 minutes, it is because some weak link in the data flow, is slowing things down. There are a few self-explanatory progress bars for progress bars. The empty bar appearing, and meaningless movement or gradients flowing in it, before it starts properly advancing. Some progress bars never properly advance, because for some reason, it doesn't even seem to know how big the file is, and so it just shows progress, but not the percentage of completion. It could be because of a gap in the programming, that it is not fully compatible, so some of the progress calculation data is missing. Sometimes, well especially in a free or beta version, it is more important that it works, than just how great its performance level is. The circle going around, that often means, hold on for a moment, I actually am doing something. And to have better self-explaining error messages would be helpful. "Internet connection is not responding, attempted to reset the connection." "Re-requesting the file, due to request time-out." I get so tired of crappy software, in which the circle or beachball goes round and round, and you walk away for a minute and come back, and still nothing has happened. Surely a computer can diagnose when no progress is occurring or when the data link has gone down and do something appropriate about it. Not just tease the user and pretend to be working on it. When I was in college long ago, and the Macintosh lab was jam-packed with users, I tried a curious experiment. I needed to make a copy of an 800K Mac-formatted 3.5" disk. Problem was, I had no Mac. I had an Apple //e computer with a mail-order 800K disk drive. Hmm. Both computers made by Apple. Both 800K, both using the same type of disks. Hmm. I suspected they could be undocumentedly compatible, even though supposedly they were not. I ran a disk copy. The copy disk verified noticeably faster than the Mac original. Wow. Really? An improvement? Not so much. I knew enough about how they work, to know what had happened. My Apple //e used the wrong sector interlace ratio. It used 4 to 1, and it was supposed to use 2 to 1 for Macintosh. 4 to 1 only optimized it for use on my //e and not on the Mac. That incorrect ratio Mac disk would run slower on a Mac. 4 disk spins would be required to load the entire track, where otherwise it would only need 2. That was back in the days, when most all the work was dumped onto the CPU. The //e was so slow, that it needed a 4 to 1 ratio, to have enough time to process the disk data before it could be ready to read the next sector. The Mac 2 to 1 ratio was causing it to miss the next consecutive sector, and so it had to wait for an entire turn of the disk to read the next sector. My copy disk worked just fine on a Macintosh. That told me in theory at least, that an Apple //e computer could technically be programmed to see, load, copy Mac files, as it was actually capable of reading and writing the data. (My interest was in writing my own OS, and also in being able to use Mac fonts on my //e.) The compatibility problem was not critical, as it did not keep it from working, only messed up the optimization. Better software could have chosen the correct ratio for Macintosh. But I guess cross-platform programming wasn't quite as big a thing as it is now? Another interesting experiment, slightly related. I liked the music on a PS1 pinball game CD. Since the PS1 often used actual CD tracks for game music, I once put the CD into my car CD player. It didn't play at first, but I pushed the next track button, and it easily played the game music. Apparently it was some sort of hybrid disk, with a game data track, and standard CD audio tracks. I doubt that that would work on later video game console disks, because I think their music tended to be some sort of compression. And earlier CD-ROM drives were actually CD players as well, meaning that they have actual audio outputs that were connected to the motherboard. I suppose if the computer crashed and froze up, the music would keep on playing? I think they may have moved away from that now, as computers became faster, perhaps the computer actually does the work of playing the CD/DVD, streaming the data, and doing all that drawing of the movie image to the computer graphics memory. And where is that "audio connection" when your optical drive now has no connection at all to the computer other than a USB cable? Surely is it 100% computer data now? Normally, I am not much bothered by a progress thermometer. They usually fill up fast enough. I just want to see that it is progressing and that the computer hasn't crashed or froze up. I had an experimental program that I wrote on my graphing calculator, that had to momentarily display a graphic image on the screen, so that it could use it as efficient storage to load all of its graphic icon variables. My little progress thermometer filled in just a second or two. Just drawing/updating the progress thermometer, probably slowed down the load by 30%?

    Many years ago (like 1985) I took my favorite class in computer science where we spent an entire semester basically working up to understanding the "Does P = NP?" problem. I even had a well-selling t-shirt made up with that question on it. This video does an excellent job getting the basic idea across in ten minutes.
