Leela Author: Gian-Carlo Pascutto License: proprietary Category: player : Windows Reads format(s): sgf Writes format(s): sgf Stable Version: 0.11.0 (dec.'17) Development status: active Homepage: sjeng.org Size of installer: 18mby Size if installed: 27mby Strongest play: 4d [2] (october'16) Plays online: LeelaBot, KGS Infos last checked: Leela is a Go playing program by Gian-Carlo Pascutto, author of the strong chess program Sjeng. As of May 2016, the website states that Leela plays at the 4 dan level on a 19x19 board, and at a high dan level on a 9x9 board. The full version is now free. Leela should not be confused with the more recent, stronger bot Leela Zero; the names are similar only due to having the same lead author, but they play quite differently. Features. At 9x9, her strength is around 1 dan ( https://www.britgo.org/junior/improve) board sizes 9x9 up to 37x37 rated games on 9x9 and 19x19 board handicap up to 100 stones auto adjust (rated games) or preset playing level engine games on up to 37x37-board (25x25 for version 0.7.0) show territory, show moyo analyze mode plays always with komi x.5 asymmetric time settings possible (free games) switch sides (by menu "Game" - "Force computer move") Website. http://www.sjeng.org/leela.html https://github.com/gcp/Leela. Implementation. According to its web site, Leela is a mix of different approaches. It seems to use a Monte Carlo engine and Deep Learning. Strengths. Like other Monte Carlo programs, it performs well against traditional Go programs. Leela likes to make a large moyo in the center, which often compensates for the opponent having all four corners. Leela often finds interesting moves that really annoy its opponent, and I'm not sure yet whether these moves are tesujis or aji keshi. In the opening, Leela often plays a shoulder hit, even against a stone on a hoshi. After doing this in some corners, these stones form a large but loose center moyo. If the opponent misses the chance to invade, this moyo becomes the winning factor. Especially in the opening, Leela often plays moves that single-digit kyus want to answer, for example attaching at weak stones or enclosing a group in a corner. This means that Leela can often control what's happening on the board. At any point of time, Leela has a good estimate of counting points, which may even allow abandoning a large group. Weaknesses. Leela likes to play long sequences of ataris. Against weaker players this often works, but stronger players can easily beat the engine by playing solidly. Like GNU Go, its impression about the status of groups isn't always correct, and sometimes it just misses to save a large group from being killed. If you're a single-digit kyu player, you may try taking all four corners and then destroying Leela's center moyo. Just take care that the moyo border doesn't become water-proof. This works well for me. Programmed to win by few points, she did not play best endgame and may stupidly fill own space to reduce the wining score. She did not count the final results in term of points ahead. She can be shocked by a good strategic move. She does not accept an integer Komi. She regards some moves as the best moves but actually they are not. She cannot learn and improve her skill from her previous games. Online versions. Leela is playing 19x19 games on DragonGoServer. It runs with a thinking time of 1 minute without GPU support. It's strength there is 5 dan. Last Update: July 2020. Download Lc0. The latest stable version of Lc0 is v0.27.0 .

Download free Chess Engines. is the unique software which is built into the program shell (e.g. "", "Arena", "Shredder") thus multiplying the force of the game shell. For example, "Kasparov Chess" is very good and clever shell. The maximum rating which can be set in it is 2600. And the rating of the chess engines reaches 3000-3200. That is why the chess engines are so popular. Where do the chess engines originate from and who makes them? This question is not trivial, vice versa it is quite actual, so it is worth talking about. The first record of the chess engine was made about 20 years ago. That was just the time when the UCI standard was developed - the universal chess interface, allowing the chess engine to be connected to the graphic interface of the program shell. The engine made to this standard can be easily connected to any chess program. The standard was worked out by Stephan Meyer-Kahlen , German programmer, who was born in 1968 in Dusseldorf. He is also the founder of one of the most famous chess programs - Shredder, which is the 12-times world champion among chess machines. The UCI standard was presented to the world by Rudolf Huber. The standard has great advantages. For example, if the engine does not save the database of the games played (although it is better if this task is performed by the engine), then one can easily manage this database by UCI. As the UCI protocol is absolutely free, it gives it the advantage over the other protocols. It can be used for private purposes and as the open-source as well. This protocol was used by only a few programs until Chessbase Company (producing Fritz) began to support this protocol in 2002. Nowadays, this protocol is used by about 100 chess programs. The majority of the chess engines are made very thoroughly and published in the net absolutely free of charge. In Russia there are the developers making engines, as well. E.g. SmarThink developed by Sergey Markov, GreKo developed by Vladimir Medvedev, Strelka developed by Yuri Osipov. These engines, as well as many others, can be downloaded from our website. As the number of the chess engines is growing, we chose the best ones, as there is simply no possibility to present all of them here. 13.01 Version Windows. Komodo 11 Version Windows 64.

Where to play Leela online? The play.lczero.org web site where everyone could quickly play Lc0 online is currently down. But even while it doesn’t work, there are some options to play Leela online. The easiest way is to play on lichess . You can pick one of the Leela Chess Zero bots: -- full-strength bot which is kept reasonably up to date. -- the bot configured almost not to think. It still very strong, but sometimes misses non- trivial tactics, which makes it possible to win. -- distilled 48x5-se network from id11258 (small network learnt from large Leela net), played on Raspberry Pi 3 with almost no thinking. -- distilled 112x9-se network from id11258, running on CPU. Also there are other bots of different configurations and strength. Check the all-the-leelas lichess team and pick the one which is online. You are also welcome to host your own Leela and join that team. If you know other ways to play Leela online (FICS, etc), please reply in comments, I’ll add it to this post. And of course you can always download Leela and set it up to play locally. [This blog post](../../../2018/09/guide-setting-up-leela-on- chess- gui.html) describes how to do that. UPD: Kontrachess has a way to play with LCZero. It seems very to be very nice looking site! I did not try it myself though. (Initially I thought it was a paid site, but one of the site representatives said in comments below that it’s actually free). Leela. Leela is a strong Go playing program combining advances in Go programming and further original research into a small, easy to use graphical interface. It is freely available, making it an ideal introduction to the game. Features. Strong Go engine including support for multiple processors and GPU acceleration Strength over 9 dan on 19 x 19, depending on hardware 2008 Computer Olympiad Silver (9x9) and Bronze (19x19) medalist Featuring Deep Learning technology Easy to use graphical interface Adjustable board size (up to 25x25!), playing levels, handicap and komi Fixed strength and time based difficulty levels Chinese rules with positional superko SGF format loading and saving Rated game mode with auto-adjusting difficulty levels Analysis features including critical variations for each move and winning odds Graphical display of critical moves, territory, best lines, … Download.

Screenshots. Analyzing a game, showing the most probable moves. What's this Deep Learning technology? Leela contains an AI technique modeled after the human visual system and brain, a deep stack of artificial neurons processing visual input with each layer combining the previous ones into higher level features (a so called DCNN, deep convolutional neural network). This "neural network" has been trained with more than 32 million positions from high level go games and taught to predict which moves a pro player would most likely consider. In 19x19 games the engine will query this deep "neural network" during the search to focus on the most critical variations. The result is a substantial raise in playing strength (about 6 stones), and a more human-like playstyle, while still allowing the engine to innovate of its own. What's the benefit of GPU Acceleration? A GPU is typically much faster than a normal processor at doing the kind of calculations the Deep Learning algorithms need. For example, an AMD R9 390 (mid-range videocard) can find the worthwhile moves in a Go position about 15 times faster than an Intel Core i5-6600 (mid-range CPU). Leela makes use of this to explore variations deeper and in more detail. You can notice that in analysis mode the critical variations displayed by the engine are much longer when GPU Acceleration is used. What do I need to run the "GPU Accelerated" version? You need a video card with OpenCL 1.1 (or later) capability. This is supported on all recent AMD and NVIDIA cards. Make sure the latest drivers for the video card are installed. The detected video card can be seen in the Help->About menu. Can I run the "GPU Accelerated" version on the built-in graphics of my CPU? This only makes sense if the built-in GPU is faster at doing the Deep Learning calculations than the CPU itself. Intel CPUs are typically very fast, with a weak built-in GPU, so this is not recommended. AMD APU's typically have a slow CPU but a fast GPU, so it would be worthwhile on those. My Linux distribution is not listed. You have several options: The "engine only" download has Linux binaries included that should run on almost all distributions, and which can be used with any Go GUI that supports the GTP protocol (almost all of them do). A good looking one is Sabaki. To use the OpenCL version you must have OpenCL drivers and an OpenCL ICD loader installed, please see the included README.TXT. The Windows installer and graphical interface work and are fully functional under wine-1.9.23 or later, although GPU acceleration will not work. Many Linux distributions have some way to take in Ubuntu/Debian packages and convert them to the distributions' own format. Perhaps someone has already done this for you. Look around! Why does Leela report >100% or negative winrates? Being sure of winning the game with 0.5 points corresponds to 100% winrate. Bigger margins of victory are represented by >100%. How do I analyse games? Enable the Analysis Window via Analyze→Analysis Window. Start analysis with F2 (or the toolbar) and move through the game with the arrow keys, looking for jumps in the Win% of the best move (the one on top). These represent mistakes by one of the players. Look at what moves Leela suggests instead. Show Network Probabilities (F3) and Show Best Moves (F4) can help understand direction of play mistakes and Show Territory (F5) can help understand the "size" and "temperature" of plays. You can "save" the position by pressing the +, then try out a variation on the board. Then do Analyze→Revert to Stored (Alt-M) to go back to the position you saved. The position is also saved whenever you enter Analyze mode. Enabling the Histogram (Ctrl-H) shows a graphical display of who was ahead at what point of the game. It plots winrate versus move number. A steep vertical bank in the line represents a likely mistake according to Leela. You can go to that move by clicking inside the Histogram window. What do the columns in the Analysis Window mean? Leela always orders the moves in this window from best to worst, i.e. the top move is the best move (so far). You can click in this window to show the principal variation for the selected move on the board. Simulations: the number of Monte Carlo playouts used to investigate the move. More simulations means more confidence in the winrate as the move has been investigated deeper. Effort%: the percentual amount of search effort Leela has spent on a move. A large search effort means that the move has consistently looked good throughout the search. Leela generally prefers such moves, unless a new very promising candidate has popped up. Win%: this represents Leela's best guess as to how likely it is for the player to move to win the game. If there is a move that is not investigated deeply yet, but appears to provide a higher chance of winning than the current best move, it is bolded. You might want to let Leela analyze a bit longer if this happens. MC Win%: the likelyhood that the player to move wins the game, as determined by randomized Monte Carlo playouts from the current position. This is a factor in the Win% calculation. Net Win%: the likelyhood that the player to move wins the game, as determined by analyzing the position with a neural network. This is a factor in the Win% calculation. Net Prob%: the probability that a pro player would play this move, as estimated by the Neural Network. Eval: displayed in non-19x19 games instead of Net Prob%. A dimensionless number expressing the likelihood of the move being good, based on a pattern database and the moves' features. PV: the principal variation. The sequence of suggested moves for both players that Leela believes is optimal. My Mac is complaining that Leela can't be opened because it is from an unidentified developer. Right click the download and select Open. You'll get the option to bypass the warning. Explanation from Apple. Leela says that white is more likely to win when black gets handicap stones. Leela's value network is generated from real human games, not idealized computer opponents. In handicap games, the stronger (white) player wins more often. You can look at the Monte Carlo evaluation for an assement with equally strong players.
