the opening book is easier, even a few moves would be good. it is also a way to make your program available to everyone, not just the “elite”. that is, almost everything that is now, move to "special settings". it remains just a game. for example 15k - 9d. when choosing, for example, 5k, the opening book and the network corresponding to the level are connected, etc. |

I made a new version (0.19) which adds some features for solving tsumego and L&D problems with KataGo (of course there are specialized programs for that, but to my knowledge they don't run natively on android). In the following explanation I assume that it is black's turn in the problem. The basic workflow is as follows: 1) Start KataGo with a 20b network and use AnalysisWideRootNoise=0.03 in the configuration. This widens KataGo's search so that "apparently bad" moves also receive proper attention (these contra-intuitive moves which are often the solution of a difficult problem). 2) Enter the problem position (you can use "pass" to enter several stones of the same color in a row). Make sure to end with a white stone so that it's black's turn. 3) Tap the dashed rectangle in the top row to restrict KataGo's analysis to the problem area: Set the "number of moves to restrict to region" to a high number (e.g. 30) to make sure that the whole analysis sequence is inside the problem area. Then click "Ok" and draw a rectangle on the board which includes the whole problem (by dragging from the top left corner to the bottom right one). Make it as small as possible to speed up search. 4) Tap "ponder" and wait until a clear favourite move emerges. This should be the solution. Often this basic workflow will be sufficient. But there are some hard problems which require a little "tuning": a) In L&D problems one side is enclosed. On an otherwise empty board this will give the enclosing side a winrate near 100% whether it kills or not. So the winrate difference between killing and non-killing moves will be very low which makes it very hard for an AI to find the killing one. To ease this you should "balance" the position by adding a few stones of the enclosed side in the empty corners. b) In some L&D problems the outside is not completely solid, so that it requires some reading to see that breaking through is impossible. This is no issue for human problem solvers since they know by "convention" that breaking through is not the aim. But KataGo doesn't know this and will waste a lot of time by analysing attempts to break through. To prevent this you may add some stones to the outside (as long as they don't affect any liberties or prevent forcing moves) And then there is this nasty thing called "ko": As the analysis is restricted to the problem rectangle there are no ko threats (with the rare exception of local ones). So KataGo will regard a sequence with a favourable ko as equally good as an unconditional one, and it will regard a sequence with an unfavourable ko as always failing. So if 1) the basic workflow doesn't yield a solution and you want to check for a solution with an unfavourable ko or 2) the basic workflow detects a solution with a favourable ko and you want to check for an unconditional solution, then you should add another local position to the board which provides a big ko threat for the relevant color. I use this one in the top left corner ----wb wwwwwb wwwwwb bbbbbb to provide a huge threat for black. To allow KataGo executing and defending the threat you must modify the basic workflow slightly: In the popup dialog "Region" you must enter the coordinates of the threat (B19) in "Moves allowed outside rectangle for black" and the coordinates of the defense (C19) in "Moves allowed outside rectangle for white". Keep in mind that KataGo was not designed for this use case, so don't blame it if you find a problem where all this still doesn't yield the correct solution. But in my experience it works quite often and it's fun to try. |

I made a new version (0.20) where I added an opening book after all. So you can now a) make a weak network's opening stronger b) get an "old school" human-style opening against any network if you are in the mood to do so The opening book can be switched on and off any time in the settings. |

if you start a new game (edit config, save), and before that the "opening book" and "play b" were enabled, then the first move is not saved to the log file. also this leads to errors. for example, if after the first move d16 you press the "ponder", then among the possible moves there is also the move d16! can be done after (edit config, save) to turn off "play b"? |

Yes, I will add that in the next version. |

I made a new version (0.21). It fixes the strange effect that And discovered in his last post (thanks for reporting). Moreover, I added a new option "b/w board" in the settings: If ticked, the board, stones and markers are displayed in black and white which should improve readability on e-ink displays. |

all these changes seem too good to be true, i never thought an app like this would exist. So if one uses the kyu-rank mode with the faster, optimized 20b net, will it still be as strong as the old 20b kyu rank bots? Its alot faster than leela zero now. it seems like no loss of strength from the old version playing against kyu rank 10. wow |

I made a new version (1.0) which is now also available on google play store: https://play.google.com/store/apps/details?id=net.kir.baduk_ai The 32 bit version now includes the same optimizations as the 64 bit version, so the KG 20b network is much faster. Moreover, both versions use much less storage than previous ones. |

on my tablet, the new version, KG 20b is 5-6 times faster, and does not slow down at all !!! |

it seems impossible, but the optimized KG 20b network works just as well as the original! in the position from https://lifein19x19.com/viewtopic.php?p=244851#p244851 the new network finds the right move very quickly and shows the win!!! incredible !!! |

Unfortunately, I can't test on android 11, since my device wasn't updated yet. So finding the cause of this crash requires some guesswork. I went through the changes from the last version and found one slightly "suspicious" part. So I changed that, thereby producing version 1.1. It's a shot in the dark, but please try if that version improves things for you. If it still crashes, it would be revealing to know if this also happens with the 10b network or only with the 20b one. |

@Vargo Thank you for checking all that. So it seems that something is different on android 11 which the code doesn't handle correctly. I found a change between android 10 and 11 which might be responsible for that and made a test release where this is handled https://github.com/aki65/aki65.github.io/releases/download/v1.2.0-test1/baduk_ai__arm64-v8a-rel-1.2.apk It would be very nice if you could check if that resolves the issue. |

Thanks for testing. So I made an official release (1.2) with this change (available on my github page and in play store). |

@akigo are you planning on making an optimized KG 40b network? maybe optional? |
