kandi X-RAY | miniball Summary

miniball is a Java library typically used in Tutorial, Learning, Numpy, Example Codes applications. miniball has no bugs, it has no vulnerabilities and it has low support. However miniball build file is not available. You can download it from GitHub, Maven.

A C++ and Java library to compute the miniball (a.k.a. min-circle, min-sphere, smallest enclosing sphere, etc.) of a point set. The code works for points in arbitrary dimension. It runs very fast in low dimensions and is practically efficient up to dimensions 10,000. The implementation is based on the algorithm from the paper "Fast Smallest-Enclosing-Ball Computation in High Dimensions" by Kaspar Fischer, Bernd Gärtner, and Martin Kutz (Proc. 11th European Symposium on Algorithms (ESA), p. 630-641, 2003). This project is dedicated to Martin Kutz†.

            How do purely functional languages handle index-based algorithms?
            Asked 2022-Apr-05 at 12:51

            I have been trying to learn about functional programming, but I still struggle with thinking like a functional programmer. One such hangup is how one would implement index-heavy operations which rely strongly on loops/order-of-execution.

            For example, consider the following Java code:

            This is not an index-heavy operation, in fact you can do this with a one-liner with scanl1 :: (a -> a -> a) -> [a] -> [a]:

            You need to specify the events which you want your bot to receive using gateway intents.

            Instead of

            const client = new Discord.Client();

            Use

            const client = new Discord.Client({ intents: [Enter intents here] })

            For example

            const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] })

            The ItemProperties component has multiple root nodes because it renders a list in the root with v-for.

            Based on the class name (infobox-item-properties), I think you want the class to be applied to a container element, so a simple solution is to just add that element (e.g., a div) in your component at the root:

            Group and create three new columns by condition [Low, Hit, High]
            Asked 2022-Feb-10 at 16:22

            I have a large dataset (~5 Mio rows) with results from a Machine Learning training. Now I want to check to see if the results hit the "target range" or not. Lets say this range contains all values between -0.25 and +0.25. If it's inside this range, it's a Hit, if it's below Low and on the other side High.

            I now would create this three columns Hit, Low, High and calculate for each row which condition applies and put a 1 into this col, the other two would become 0. After that I would group the values and sum them up. But I suspect there must be a better and faster way, such as calculate it directly while grouping. I'm happy for any idea.

            To avoid that warning you just need to remove that API usage from your project. Remove these lines of code from the AndroidManifest.xml file.

            Previously, Android Flutter apps would either set io.flutter.embedding.android.SplashScreenDrawable in their application manifest, or implement provideSplashScreen within their Flutter Activity. This would be shown momentarily in between the time after the Android launch screen is shown and when Flutter has drawn the first frame. This is no longer needed and is deprecated – Flutter now automatically keeps the Android launch screen displayed until Flutter has drawn the first frame. Developers should instead remove the usage of these APIs. - source


            UPDATE (FLUTTER 2.8.0)

            As per the flutter 2.8.0 update, The newly created project doesn't have this warning.

            They removed unused API from Androidmanifest.yml but still have belove mentioned code.

(More documentation to come. Contact us in case you run into any problems.).
            On MacOS, do the following (not yet made on other ). Do note that if you use it for a project, you might have to copy over the code to that specific project, as it has not been set up so it would be installable through pip.
            Stand in the python-folder.
            Run g++ -o miniball_python.so -shared miniball_python.cpp.
            Run pytest (if you do not have it, install it through pip install pytest) to see that it works and that all tests pass.
