Thanks
the code is open source so took a look. Looks like it's using gnu go's score estimator, but could be wrong, will take closer look.

Hi, I was wondering if anyone new of any good open source score estimator for none final positions? If it can recognize some life and death that would be great. Preferably in c# but any language would do. |

Check with Justin Kramer, who runs eidogo.com. He used to have one on his site. EDIT: He still has an icon for it, but clicking on the icon generates a message to the user saying that the estimator is inactive because it was using too many clock cycles. So he presumably still has the code. |

Score Estimator used by OGS : https://github.com/online-go/score-estimator |

Are you sure that code is for the in-game "score estimate" below the player names, which is extremely simple and useless as you describe (even worse than useless I think as it misleads beginners), and not the better score estimate function which can be accessed from the 'game menu icons' of a little speedometer. The latter is similar to the KGS one: not perfect but does estimate not-yet-completely-surrounded likely territory. |

Yes, you are right. I had looked at it one time early in a game and it gave nothing of value so I had not bothered with it again. I just looked and it gives a little more, but still misses a lot of point until late in the game, |

You could have gnugo "play out" the game and then use that score. |

Thanks for suggestions, using OGS to find dead stones and then use a Bouzy 5/21 algorithm might give decent results. Yes gnu go gives good result but haven't found a good way to visualize it, only a score. Want to show where the territory is coming from. |

Got some decent result. Used Gnu Go to find probable dead stones and run a Bouzy 5/21 algorithm to get an estimate. Looks like it's working OK.

As pointed out here: lifein19x19.com/forum/viewtopic.php?f=18&t=13692 Leela has an "mc_score" command. So you can type (in the commandline engine): loadsgf myffile.sgf mc_score And Leela will reply: = B+5.5 i.e. black up 5.5 points. |
