The Erdős–Szekeres theorem is a significant result in combinatorial geometry and discrete mathematics. It addresses the problem of monotone subsequences in sequences of points in the plane. The theorem states that for any integer \( n \), any sequence of \( n^2 \) distinct points in the plane, no three of which are collinear, contains either: 1. An increasing subsequence of length \( n \), or 2. A decreasing subsequence of length \( n \).

Percolation critical exponents describe how certain quantities behave near the percolation threshold, which is the critical point at which a system undergoes a phase transition from a non-percolating state (where clusters of connected nodes are finite) to a percolating state (where a connected cluster spans the entire system). These exponents characterize the scaling relationships of various properties of the system as it approaches the critical threshold.
A **random recursive tree** is a type of random tree structure that is constructed using a specific recursive method. It is commonly studied in the fields of graph theory, combinatorics, and probability theory. Here's a brief overview of how a random recursive tree is typically constructed: 1. **Construction Process**: The construction of a random recursive tree starts with an empty tree. You then add nodes one at a time.
A Random Tree is a type of decision tree model that is typically used in the context of ensemble learning methods, particularly in algorithms like Random Forests. Here are some key points about Random Trees: 1. **Basic Concept**: A Random Tree is a decision tree that makes splits based on a random subset of features and data points. This randomization helps reduce overfitting, which is a common problem in standard decision trees.
The Soft Configuration Model is a conceptual framework used primarily in computer science and systems design, particularly concerning software architecture and configuration management.

Pinned article: 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!
We have two killer features:
  1. 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-calculus
    Articles 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.

  2. 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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
