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”.
The problem to determine all positive integers such that the concatenation of and in base uses at most distinct characters for and fixed [citation needed] and many other problems in the coding theory are also the unsolved problems in mathematics.

A power problem: control or change is difficult when the technology has become entrenched. The idea was coined by David Collingridge at the University of Aston Technology Policy Unit in his 1980 book The Social Control of Technology. [1] The dilemma is a basic point of reference in technology assessment debates. [2]
