When the problem calls for a minimal traversal of a digraph (or multidigraph) it is known as the "New York Street Sweeper problem." [13] The k-Chinese postman problem: find k cycles all starting at a designated location such that each edge is traversed by at least one cycle. The goal is to minimize the cost of the most expensive cycle.
The mixed Chinese postman problem (MCPP or MCP) is the search for the shortest traversal of a graph with a set of vertices V, a set of undirected edges E with positive rational weights, and a set of directed arcs A with positive rational weights that covers each edge or arc at least once at minimal cost.

Technopoly: The Surrender of Culture to Technology is a book by Neil Postman published in 1992 that describes the development and characteristics of a "technopoly". He defines a technopoly as a society in which technology is deified, meaning “the culture seeks its authorisation in technology, finds its satisfactions in technology, and takes its orders from technology”.
A problem is NP-complete if, roughly speaking, it is in NP and is not easier than any other NP problem. Many combinatorial problems, such as the Knapsack problem, the travelling salesman problem, and the Boolean satisfiability problem are NP-complete. For all these problems, the best known algorithm has exponential complexity.
The study, which followed healthy older adults for 5 years, found that antibiotic use was not associated with an increased risk of cognitive impairment and dementia.
Neil Postman (March 8, 1931 – October 5, 2003) was an American author, educator, media theorist and cultural critic, who eschewed digital technology, including personal computers, mobile devices, and cruise control in cars, and was critical of uses of technology, such as personal computers in school.
