It was great. 01:38:22 Do you understand PVS/Scout? 01:38:37 I would like to improve my understanding of the whole null window search deal. 01:39:05 No I don't. 01:40:59 I could barely expand PVS without looking it up. My first thought was what theorem provers have to do with all this. 01:47:40 shachaf How did you use Alpha Beta without the use of comments? 01:48:23 I did rewrite my cellular automaton update function for Ponder This in assembly though, just for laughs... it ended up 20% faster than the corresponding C, which I think is decent nowadays. 01:48:48 Did you do some sort of fancy SIMD thing? 01:48:50 In assembly langauge for what instruction set? 01:48:50 > 1/1.2 01:48:52 0.8333333333333334 01:48:56 no SIMD at all 01:49:23 or is that 16% faster... 01:49:50 16 and 2/3 01:50:02 jonathanr: it's not that precise 01:50:08 or accurate 01:50:47 > 21/25.5 01:50:49 0.8235294117647058 01:50:54 > 25.5/21 01:50:56 1.2142857142857142 01:51:12 Using fractions is more precise than decimal, unless I find a way to write ­­¯ over the numbers 01:51:18 (those are the approximate cycle counts) 01:51:34 shachaf: I did think about it but I don't think it'll pay off. 01:52:13 shachaf: The proper way to do SIMD is to move it to a GPU, which will be much slower for an individual update but make up for it by massive (compared to CPU) parallelization. 01:52:33 Sure. 01:53:09 Do you like this? where this = alpha-beta pruning 01:53:20 `? this 01:53:22 This is something people on the channel like to talk about. We're often unsure what this is, though. Nobody likes this. 01:55:49 shachaf: The trouble is, 128 bit shifts are not a good fit for Intel's SIMD stuff. With x86_64 you have those cute shld/shrd instructions. To do that in SSE, you need to shift, then use the weird byte-wise shift on top, then shift in the other direction, and combine the results. And I think the CPU can issue twice as many integer operations as SSE instructions. 01:56:35 But I didn't try. 01:57:34 It's great how you use these tricks to do an exhaustive search of a game tree to depth 13 or however much. 01:57:38 Such a big tree. 01:57:46 (gcc knows how to use the shld/shrd instructions, too. The speedup I have is mostly from better instruction scheduling... I save a few mov instructions as well, but those are essentially free.) 01:58:40 Those modern CPUs are such beasts. 02:00:46 not %rax; or %rbx, %rax <-- as far as I understand it, this fuses into a single micro-op. My first instinct was to move the `not` instructions further up to get rid of a data dependency and stall... and that made the code slower. 02:02:19 I don't really like the way they do it so much, though. I like MMIX instruction set. 02:02:24 And the CPU will reorder instructions on its own as well... 02:02:54 * int-e shrugs. 02:03:07 Nobody uses MMIX though. 02:04:13 "the CPU" is an i7-6850K; I expect Ryzen does similar things. The low power models are less crazy. ARM as well, I suppose. 02:04:27 (That is, ARM is less crazy as well, I suppose.) 02:05:26 There is not suitable hardware for MMIX made yet (other than a few FPGA stuff which is incomplete, as far as I know), although there are software implementations of MMIX that can measure the number of cycles. 02:07:46 TBH I have not even read the MMIX document, because I hardly see the point. 02:09:22 Well, I think that it is a better instruction set than ARM and some other stuff. However, there is a few things I would have done differently, such as I would have explicit caching only and no implicit caching, and I would also have a "Muxcomp" operator. 02:57:48 -!- adu has joined. 03:47:18 -!- tromp has joined. 03:51:13 irony; I just realised that I had been "incorrectly" thinking of RBF as a group but actually had the concept of monoid in mind.

I never even implemented function/subroutine calls, even though that would have made more programs runnable. I'm not sure I understood back then how to implement function calls with parameters and local variables in an interpreter. 19:15:25 But the bigger problem is that there are parts where I kept modifying the source codes of psz programs to match the interpreter, rather than working harder to implement the syntax that the existing programs used. 19:15:36 At least I had the sense to mark with comments where I modified the programs, but still. 19:16:27 For example, many psz programs are missing keywords to mark the end of if/while statements. However, they do always have newlines and indentation determine where each if/while ends, so I should have modified the parser to ignore those end keywords and look at the indentation. 19:17:20 I also didn't implement print statements that print literal strings and variables in the same statement, even though multiple psz programs use that, instead I just modified those statements in the programs. That's rather silly. 19:17:56 In the end there are only like five programs that the interpreter can actually run. 19:18:23 The coding style of the interpreter sucks, but then, so did the coding style of every program that I wrote back then. 19:18:37 what is psz 19:19:18 myname: It's an interpreter. (1) You don't want to know. (2) If you really want to know, "http://www.math.bme.hu/~ambrus/pu/psz-snapshot.tgz" . 19:22:59 also because of this, I never really did anything with the results of the runs 19:23:06 so the goal failed too 19:23:26 What even is this? 19:24:18 This looks foreign language but not *extordinarily* esoteric 19:26:47 Lymia: it's about KöMaL's mail-in programming competition between 2001-09 and 2003-01, to which the organizers released example solutions (after the deadline) in this nonsense language with no consistent syntax rules, 19:27:32 presumably because if they released solutions in a production language that people can just get a compiler for (like pascal or C; they did occasionally did that for a few tasks), anyone could run their example solution and see that it's broken. 19:28:28 So I decided to try to run those example solutions again to see that they are indeed completely broken, darn the obfuscated language they're written it, and indeed found that at least the example solution for I.10. is broken. 19:28:35 But I never really got far with it. 19:29:09 the tasks and solutions are linked from https://www.komal.hu/verseny/korabbi.h.shtml with the relevant dates, 19:29:23 language barriers yay 19:29:45 plus the tasks are also linked from https://www.komal.hu/verseny/korabbi.e.shtml in English translation 19:30:05 the solutions aren't, but at least the source codes for the solutions shouldn't require translation, even if the explanations do 19:30:46 at least one of the early solutions that they released in Pascal is broken too by the way, which may have discouraged them from releasing real runnable programs 19:31:42 and I don't mean broken as in it has a few portability problems or it fails in some weird corner case, but that the program source code is entirely not powerful enough to do what the problem asked for 19:41:43 ... eek. 19:42:47 Note that this was back between 2001-09 and 2003-01. Me and everyone else were very young back then. And it's not like they had much money to pay to the college students that they roped in to write most of those problems and solutions. 19:42:53 So there are excuses. 19:43:14 Believe me, the programs I write these days are better. They're not perfect of course, but they're buggy in more advanced way, 19:43:25 and I managed to write larger programs that are still usable. 19:44:15 Plus the internet was young, there weren't many opportunities to learn good practices from others yet. 19:45:56 Also KöMaL had a homepage where they listed a copy of those programs and solutions (besides the printed journal), but it only added a forum to the homepage in 2003-11 apparently, so I couldn't really talk to many people about those example solutions either. 19:51:27 b_jonas: isn't I.10 just a simple convex hull? 19:52:12 gnu-nobody: it's supposed to be, yes. but the example solution is broken. 19:53:13 Also as far as I can see the solution is using an O(n^2) sort 19:59:56 gnu-nobody: the larger problem is that the solution usually runs into a division by zero 20:05:38 if you're talking about sorting the stuff by atan2 (I didn't read the code actually) there is a near-trivial way to bypass that 20:05:48 except I don't remember it 20:08:23 gnu-nobody: yes, there are better ways to write that program. that's not the question. 20:09:14 Algorithms code is nasty in general. 20:09:17 So easy to fuck everything up. 20:17:44 -!- kspalaiologos has quit (Quit: Leaving). 20:18:06 -!- gnu-nobody has quit (Ping timeout: 265 seconds). 20:57:49 [[User:PythonshellDebugwindow]] M https://esolangs.org/w/index.php?diff=72282&oldid=72249 * PythonshellDebugwindow * (+51) 21:08:01 -!- rain1 has quit (Quit: leaving). 21:08:20 -!- TheLie has joined. 21:14:36 [[User:PythonshellDebugwindow/(Unnamed language)]] M https://esolangs.org/w/index.php?diff=72283&oldid=70948 * PythonshellDebugwindow * (+2390) 21:31:05 -!- atslash has quit (Ping timeout: 265 seconds). 21:31:19 So. 21:31:29 I'm tempted to give BFJoust one last spurt of life before I clean my hands of this. :p 21:31:34 A last attempt at an evolver. 21:31:45 -!- atslash has joined. 21:32:14 -!- Lord_of_Life has quit (Ping timeout: 240 seconds). 21:32:24 -!- Lord_of_Life_ has joined. 21:35:16 -!- Lord_of_Life_ has changed nick to Lord_of_Life. 21:44:02 I am still work on TeXnicard and on the card set that I was making with it.
