Players who watch BadukClub event streams will notice that we provide an Ai evaluation for viewers. But often times viewers also have questions about what they are seeing so I figured I'd explain things here. Firstly, credit needs to go to Jeremiah Donley for building the ai evaluation tools. I made the design and he coded the project and also spins up the servers every time we need him too. Okay, so what are we seeing here? From top top to bottom we are seeing the time ported directly in from OGS. It's also worth mentioning that this tool is only usable on games which occur on OGS. Underneath the time is the players OGS usernames. Often times though those usernames don't match the player names so for now we also show the player names and images (and sometimes cameras) on the stream as well. In the top middle we have the win-rate percentage inside of a colored circle with a circular bar graph wrapping around it. The quantity of black/white on the bar graph matches win-percentage. And this win percentage is calculated first by Katago and then run through an equation to take into account the rank of the players. This equation was created by Professor Quentin Rendu PhD. He gave a talk about his research at the ISGS 1st International Conference on Go Studies (watch the video here). The color inside the circle also matches the color of the small circle played overtop of the last move made in the game. The colors match the evaluation colors used by Lizzie. We also added little dots ordered good to bad on the side. Blue means the ai preferred move, green is great, yellow is okay, red is bad, and purple is a blunder. Lastly, on the bottom we display the points each player has using Area or Chinese counting. The reason for this is for new player intuition. The concept is to display the number of (estimated) points that each player has. However, those with sharp eyes will notice that the black and white bars have a gradient based on the solidity of those points. Additionally, there is a dotted line in the middle representing the required points needed by each player to win! So it becomes a visual experience of watching the points grow for each player as they race to occupy more than half the board before the other player. And of course this accounts for Komi, however it doesn't display the "half-point" awarded to white to break ties and instead puts the dotted line slightly off center in whites favor.
