Note that odd permutations don't form a subgroup of the symmetric group like the even permutations do, because the composition of two odd permutations is an even permutation.
Jacques Mering is likely a reference to a French mathematician known for his work in the field of mathematics, particularly in the areas of analysis and number theory.
Generalization of AlphaGo Zero that plays Go, chess and shogi.
- www.science.org/doi/10.1126/science.aar6404 A general reinforcement learning algorithm that masters chess, shogi, and Go through self-play by Silver et al. (2018), published without source code

www.quora.com/Which-chess-engine-would-be-stronger-Alpha-Zero-or-Stockfish-12/answer/Felix-Zaslavskiy explains that it beat Stockfish 8. But then Stockfish was developed further and would start to beat it. We know this because although AlphaZero was closed source, they released the trained artificial neural network, so it was possible to replay AlphaZero at its particular stage of training.
"Discoveries" by Erich Meyer is not widely recognized as a specific work or publication in mainstream literature or academic circles up to my knowledge cutoff in October 2023. There may be a few different interpretations or contexts where the name might appear, such as a research article, a book, or even a project related to a specific field.

Very good channel that gives some idea of the behind the scenes of working with card stores and secondary market trading.
Such lessons can have applicability in business and investment outside of the Magic The Gathering context as well. Yet another example that usefulness can come out of uselessness.

Helen Megaw is an accomplished scientist known for her contributions to materials science and crystallography. She has been involved in research related to the properties and structures of various materials, particularly in the context of mineralogy and the study of crystalline substances. Megaw's work has significantly contributed to our understanding of the relationships between crystal structures and their physical properties. In addition to her research, she is also recognized for her role in academia, particularly in mentoring students and contributing to scientific education.
A Security Association (SA) is a concept used in network security that defines a relationship between two or more entities that establishes mutual security services and parameters for secure communication. It is a key part of security protocols, such as Internet Protocol Security (IPsec) and Internet Key Exchange (IKE). ### Key Components of a Security Association: 1. **Security Parameters**: Defines the parameters for security operations, including the algorithms used for encryption, hashing, and authentication.

Visual cryptography is a cryptographic technique that allows for the encryption of visual information (such as images) in such a way that decryption can be performed visually without requiring complex computations. The concept was introduced by Adi Shamir in 1994. In visual cryptography, an image is divided into multiple shares (or parts) in such a way that each share alone does not reveal any information about the original image.
Pinned article: ourbigbook/introduction-to-the-ourbigbook-project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page. View it live at: ourbigbook.com/go/topic/derivativeVideo 2. OurBigBook Web topics demo. Source. - local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control

You can also edit articles on the Web editor without installing anything locally. Video 3. Edit locally and publish demo. Source.
