The Canadian Traveller Problem (CTP) is a combinatorial optimization problem that extends the classic Travelling Salesman Problem (TSP). It arises in scenarios where a traveller must visit a set of locations (cities or nodes) while adhering to certain constraints.
In type theory, a "container" is a type that can hold or "contain" elements of a certain type and has a structure that allows for certain operations to be performed on it. Containers are a way to abstractly represent collections of items in a type-safe manner. ### Key Concepts of Containers in Type Theory: 1. **Type Parameters**: Containers are often parameterized by types.
Water scarcity refers to the lack of sufficient freshwater resources to meet the demands of water usage within a region. It occurs when the demand for water exceeds the available supply or when quality limits the use of water. Water scarcity can be classified into two main types: 1. **Physical Water Scarcity**: This occurs in regions where there is not enough freshwater to meet the needs of the population, often due to factors such as climate, geographic location, and environmental conditions.
Homology theory is a branch of algebraic topology that studies topological spaces through the use of algebraic structures, primarily by associating a sequence of abelian groups or modules, called homology groups, to a topological space. These groups encapsulate information about the space's shape, connectivity, and higher-dimensional features.
"Categories for the Working Mathematician" is a foundational textbook in category theory written by Saunders Mac Lane, first published in 1971. The book is widely regarded as one of the most influential works in mathematics, particularly in the fields of algebra, topology, and mathematical logic. Category theory itself is a branch of mathematics that focuses on the study of abstract structures and relationships between them. It provides a unifying framework for understanding and formalizing concepts from various areas of mathematics.
Hironaka decomposition is a concept in the context of algebraic geometry and singularity theory, specifically related to the resolution of singularities. The term is often associated with the work of Heisuke Hironaka, who is well-known for his theorem on the resolution of singularities in higher-dimensional spaces.
Alan Lindsay Mackay is a prominent Australian mathematician known for his work in the field of mathematics, particularly in relation to partial differential equations and mathematical analysis. He has contributed significantly to various areas within mathematics and has published numerous papers throughout his career.
Bernice Weldon Sargent does not appear to be a widely recognized figure in public records or history based on the information available up to October 2023. It is possible that she is a private individual or someone with a localized significance not covered in mainstream sources.
The Berry–Esseen theorem is a result in probability theory that provides an estimate of the convergence rate of the distribution of a sum of independent random variables to a normal distribution. Specifically, it quantifies how closely the distribution of the standardized sum of independent random variables approaches the normal distribution as the number of variables increases.
The term "European grid" can refer to several different concepts depending on the context. Here are a couple of common interpretations: 1. **European Electricity Grid**: This is the interconnected electrical grid that spans various countries in Europe. It allows electricity to be transmitted across borders, facilitating the integration of renewable energy sources and improving overall energy security and reliability.
Bill Warner is an author and researcher known for his work exploring the intersection of history, politics, and religion, particularly focusing on the Islamic world and its impact on Western civilization. His writings often delve into the historical context of Islam, examining its growth, influence, and the relationship between Islam and Western societies. Warner is also known for his controversial views and interpretations, which have sparked discussions and debates.
The term "binding neuron" is not widely recognized in mainstream neuroscience terminology, but it can refer to concepts in cognitive neuroscience or computational models related to how the brain integrates and binds information from different sensory modalities or cognitive processes. In a general context, "binding" refers to the process by which the brain combines disparate pieces of information (such as visual, auditory, and tactile inputs) to form a coherent perception or understanding of an object or event.

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
