31Transformation problem — In 20th century discussions of Karl Marx s economics the transformation problem is the problem of finding a general rule to transform the values of commodities (based on labour according to his labour theory of value) into the competitive prices… …
32Longest common subsequence problem — Not to be confused with longest common substring problem. The longest common subsequence (LCS) problem is to find the longest subsequence common to all sequences in a set of sequences (often just two). Note that subsequence is different from a… …
33Producer-consumer problem — In computer science, the producer consumer problem (also known as the bounded buffer problem) is a classical example of a multi process synchronization problem. The problem describes two processes, the producer and the consumer, who share a… …
34Closest pair of points problem — Closest pair of points shown in red The closest pair of points problem or closest pair problem is a problem of computational geometry: given n points in metric space, find a pair of points with the smallest distance between them. Its two… …
35Elliptic boundary value problem — In mathematics, an elliptic boundary value problem is a special kind of boundary value problem which can be thought of as the stable state of an evolution problem. For example, the Dirichlet problem for the Laplacian gives the eventual… …
36Is–ought problem — David Hume raised the is ought problem in his Treatise of Human Nature The is–ought problem in meta ethics as articulated by Scottish philosopher and historian, David Hume (1711–1776), is that many writers make claims about what ought to be on… …
37Napkin folding problem — The napkin folding problem in geometry explores whether folding a square or a rectangular napkin can increase its perimeter. The problem is known under several names, including the Margulis napkin problem, suggesting it is due to Grigory Margulis …
38Cigarette smokers problem — This article is about the computer science problem. For problems that may affect cigarette smokers, see health effects of tobacco. The cigarette smokers problem is a concurrency problem in computer science, originally described in 1971 by S. S.… …
39Firing squad synchronization problem — The firing squad synchronization problem is a problem in computer science and cellular automata first proposed by John Myhill in 1957 and published (with a solution) in 1962 by Edward Moore. The problem is analogous to problems of logical design …
40Delta L problem — The delta L problem (ΔL problem) is a condition that occurs regarding certain firearms chambers and their practical incompatibility with ammunition made for the corresponding chambering. The ΔL refers to a Commission Internationale Permanente… …
