Note: These settings should be turned off one by one with constant checking if the game now launches and plays properly as the game will look much uglier without these graphics options. Your issue should be resolved after running the game again.Besides that, you should try and turn off the grass, Frame Buffer, and softshadows options as that helped several users get rid of the crashing. Under this sub-section, locate the V-Sync option and turn it off. Try and locate the Graphics Options section and click the Advanced Options button. From the game’s main menu, scroll down and click on Options.If the game is not installed through Steam, simply locate the game’s icon on your computer and double click on it. Right-click on the game and choose the Play Game entry in the context menu.Navigate to the Library tab in the Steam window and locate Star Wars: KOTOR in the list of games you own in the library.If you have purchased the game using Steam, open up your Steam program by double-clicking its icon from the Desktop or by searching for it in the Start menu or the Cortana button (search bar) next to it (if you are using Windows 10).Not all graphic settings are bad for your setup but certain graphics cards definitely struggle running certain features so try turning them off and check to see if the game crashes. If the game actually launches and you are able to start playing, the error is probably related to graphic settings which should be turned off to prevent the often crashes. Solution 1: Turn off Various Graphics Settings Introductory video files which are played as soon as you launch the game were problematic for quite a few players.Old drivers which can’t keep up with the game’s settings or which have lost support by your current version of the operating system.In-game graphics settings which were buggy from the release or which are simply not supported by your PC’s setup.Here are some usual causes for the crashes: ![]() ![]() Some people have complained that the game is a bad port for PC from the start, as well. There are quite a few reasons which cause the game to crash on a Windows 10 and it’s impossible to pin down a certain cause. Follow the instructions below in order to try and fix KOTOR on your PC. However, Windows users (especially Windows 10) have seen that the game is almost impossible to play either with constant crashes occurring during the game or crashes right after the game is opened which prevent you from opening it at all. The game was later ported to various other devices and received nothing but praise from users and critics. Developed by BioWare and published by LucasArts, the game was released for the Xbox on July 15, 2003, and for Microsoft Windows on November 19, 2003. Star Wars: KOTOR (Knight of the Old Republic) is a role-playing game set in the Star Wars universe.

This will create an explosion, knocking everyone in the vicinity into fight for your life mode. So, we need to create two black and white sub-images. We don't need the surrounding black, as it is technically not part of the image (and we can use the ghost and circle together later on for any black that might be needed). For the Ghostbusters image, the red circle and the ghost are the two areas of interest. I have found that it works best on black and white images, so we will convert our image to several black and white sub-images first.Įach area of our image that we are interested in needs to be separated out into individual black and white image. It has a tool called 'Trace Bitmap' that will generate a set of vectors around an image. To generate the vectors from the final image, I use another free software called Inkscape. Save it in a format that has lossless compression (PNG or TIFF), or save it uncompressed (BMP). The compression will ruin all of your hard work. Now, save the image as your master image NOTE that you do not want to save this as a JPG image. After that, my image is basically 3 colors black, white, and red (there are a few shades of grey and reddish-grey at the transitions between the 3 colors, but that is OK). ![]() Everything was converted to the single red color at this time. Because of the tolerance setting I used, I only had to move the tool over the red blended area once. I proceeded to move the tool around the image, with the button on the mouse held down to keep the tool active. Finally, I ensured that antialiasing was turned off. I then increased the brush size, so that the tool covered more of the image at once, and I also increased the tolerance, so that more shades of red were recolored. I chose RED as the foreground color, and then used the "eye dropper tool" (called "color picker" in Paint.NET) to select one of the blend colors in the red slash across the ghost. I use the free image editor Paint.NET for Windows, where the tool is called "Recolor." What the tool does is replace any color found that matches the background color with the chosen foreground color. To reduce the color count in your image, use the "color replacer tool" in your favorite graphics program. It turns out that the Ghostbusters image I found has over 10 colors in it (if you zoom in on the red, you will see a blend of many shades of red). In the first photo, you can see that the tiger should only be 4 colors, and the Ghostbusters logo should only be 3 colors. Ideally, the image should only have the minimal colors necessary to represent it. To convert it to a vector, we need to manipulate/touch it up. I'll describe how to deal with JPG images in the next step.Īt this step, you should have selected an image. If you can find images in PNG, TIFF/TIF, BMP, etc., you will likely be much better off (see the 3rd photo to see how a "line" isn't a clean line in a JPG). However, for what we are trying to achieve, this can be our largest source of problems. This is fine for photo-realistic images, because the subject is usually a real world photo where soft edges and transitions are preferred. It also blurs (aliases) the lines and loses detail. Trick 3: Avoid the Ubiquitous JPEG Image, if PossibleĪlthough the JPEG/JPG format is everywhere, it highly compresses images to save space. The "Line drawing" or "Clip art" types are right up our alley, as they won't be photo-realistic (see the second photo). To avoid having to wade through those types of results, you can use the Search tools again to select the Type of image you want. Trick 2: Check the Clip Art or Line Drawing FilterĪgain, photo-realistic images are not a good candidate for vector conversions. ![]() To ensure your Google Image search returns only suitably sized images, use the search tools that are at the top of the results specifically, Search tools -> Size -> Larger than. Once the image is converted to Vectors, you can scale it infinitely large or small, without losing detail but you have to get a high quality Vector image first. The higher the resolution of your starting image, the better success you are going to have with this process. ![]() I use a few tricks to find suitable images using Google. Just be sure that if you use the image for commercial purposes that you have rights to that image. If you don't already have an image to convert, the internet is a great resource. It will not work if you are trying to convert a photograph with many colors and gradient shading. This instructable is geared towards converting simple designs with distinct edges. ![]() Metal is a great option for keeping your keys safe, and it won’t fall apart over time, but it is also rigid.

I’d say this is the most effective of the three mods in terms of impact on actual playing. It’s still not as nice as the ultra-flat low profile Les Paul buttons (by far my favorite feature of that guitar), but the buttons respond noticeably better this way, and they’re more friendly to sliding. I used a fairly thick cardboard stock behind my buttons, so maybe that’s why. The fret button cardboard mod is surprisingly effective, much more so than I would have predicted. Doing something about that gets it much closer to the nice, smooth response of the SGs (and pretty much every other good plastic guitar). The whammy bar is stupidly stiff on the stock Xplorer. I also used a bit of silicone lube spray around the strum pivots. I found it all fairly self explanatory once I opened the Xplorer up. Imagine a rubber band there instead.)Īll three of these are pretty easy to do- all you need is a small torx wrench.

The "original" MCTS algorithm used random play to guestimate the strength of a position. ![]() So where did the "Monte Carlo" name come from? Especially in the AlphaZero implementation, where there's no random play during inference / during games (!!). MCTS is very methodological despite the name. But Monte-Carlo in this instance meant "MCTS", and not "random play". Hmmm, you're right in that humans don't play randomly. Its a very elegant use of neural nets to improve the MCTS template. AlphaZero was interesting in that this manual tweaking of MCTS was left to the neural network training. Alpha-Beta search doesn't have any concept of this, and requires a Quiescence search engine "tacked on" for the feature. But its still very much a manually tweaked process: how much time to dedicate "exploring" bad moves, and how much time spent "exploiting" good moves (analyzing and making sure a "good" move is as good as you think it is). MCTS has a more elegant statistical theory behind it. The formula has some statistical guarantees about finding results that I never really understood, but hope to research and math-out one day. The precise formula involves a logarithm, division, and I think a square-root. Ex: every time you search a winning position 10,000 times, you want to search losing positions 100 times. The multiarmed bandit heuristic is to search "winning" positions more, but to "explore" losing positions less. Positions of "loss" or "draw" will be seen as a miss in the multi-armed bandit, but the "exploration" phase of the algorithm will randomly search a position anyway. Positions of "win" are seen as a "win" with a multi-armed bandit, and are explored further and analyzed further. It will NOT return until it gets that kind of evaluation. MCTS analyzes "deeper" positions, while Stockfish analyzes more exhaustively.Īnd again: classical MCTS (probably not AlphaZero) will keep going until it evaluates a position as "win", "loss", or "draw". MCTS on the other hand is almost ENTIRELY a quiescence search. Under certain conditions, Stockfish will search deeper (but not all conditions). I think my point is that Quiescence search is an explicitly programmed feature of Stockfish. Stockfish is also multithreaded and got a hash-table to remember previously searched positions (even positions from "another" branch of the tree). Stockfish uses iterated deepening as you've said, but that's very similar to Breadth-first search. Breadth-first search with Alpha-Beta pruning is how it is taught at universities. Nonetheless, the classical chess search algorithm is exhaustive. For example, Stockfish may recognize that some moves are "forced" and will iterate a specific variation deeper. The pruning in Alpha-beta is very much a heuristic that is applied on top of the template. So MCTS just naturally works with neural nets very well. which btw, performs way better than you'd expect.) might be used to "bootstrap" the exploration weights. Its possible that the original randomized MCTS algorithm (search randomly. ![]() Most of the input layers / early hidden-layers can be "recycled" between the "explore" function and the "evaluation" function.ĮDIT: I don't know how AlphaZero gets its "exploration" network trained up however. It seems like a very good way to have a single neural network mostly perform double-duty (aside from the two output nodes). It uses a neural-net to find "interesting" positions to guide the search, and the same neural net also evaluates the position (who is winning or losing). MCTS implemented by AlphaZero is different however. Think of it as a random-sample of the win/loss potential of a move. The reasoning is simple: on the average, a lot of "samples" of playthroughs will lead to a better estimate for win/loss probability. In effect, its a depth-first search, you play until you make a conclusion (potentially a "bad" conclusion). Classically, the original MCTS algorithms for Go would play all the way to the end of a game before searching other parts of the tree. Its an exhaustive search, like a breadth-first search. Monte-Carlo seems more akin to how humans play games.Īlpha-Beta pruning is the classical computer science algorithm, easier to understand, describe, and analyze. |
