On a sparse graph, Johnson's algorithm may be more efficient, taking Chris Dekker

Chris Dekker (born 6 December 1945 in Westzaan, Noord-Holland) is a former football defender and midfielder from the Netherlands, who played for AZ Alkmaar, NEC Nijmegen, DWS and FC Amsterdam, before moving to Belgium to play for R. Charleroi S.C. (1977–1981).

Dekker played his last match on 10 March 1985, and became a football manager, who coached Fortuna Sittard, FC Eindhoven, Al-Jazira (United Arab Emirates), FC Den Bosch, Qatar (– 17), RBC Roosendaal, Sparta Rotterdam and Fortuna Sittard once again.

Context of computational complexity

For example, Chan's algorithm can compute the convex hull of a set of points in O(n log h) time, where n is the number of points in the input and h is the number of points in the resulting convex hull, a subset of the input points.

Context-free language

Parser algorithms for context-free languages include the CYK algorithm and the Earley's Algorithm.

Efficient polynomial-time algorithms for the membership problem are the CYK algorithm and Earley's Algorithm.

Cornelis Dekker

Dijkstra's algorithm

The process that underlies Dijkstra's algorithm is similar to the greedy process used in Prim's algorithm.

Directed acyclic graph

In contrast, for arbitrary graphs the shortest path may require slower algorithms such as Dijkstra's algorithm or the Bellman–Ford algorithm, and longest paths in arbitrary graphs are NP-hard to find.

Elly Dekker catalogued the National Maritime Museum's collection of globes in Greenwich, east London, England.

Euclidean minimum spanning tree

The simplest algorithm to find an EMST in two dimensions, given n points, is to actually construct the complete graph on n vertices, which has n(n-1)/2 edges, compute each edge weight by finding the distance between each pair of points, and then run a standard minimum spanning tree algorithm (such as the version of Prim's algorithm or Kruskal's algorithm) on it.

Since there are O(n) edges, this requires O(n log n) time using any of the standard minimum spanning tree algorithms such as Borůvka's algorithm, Prim's algorithm, or Kruskal's algorithm.

OLT Express Germany

OLT was founded on 1 November 1958 by Martin Dekker and Jan Janssen as Ostfriesische Lufttaxi - Dekker und Janssen OHG, initially operating air taxi flights to islands in the North Sea from Emden.

Philip Massinger

The Virgin Martyr, in which Dekker probably had a large share, is really a miracle play, dealing with the martyrdom of Dorothea in the time of Diocletian, and the supernatural element is freely used.

Shor's algorithm

On the television show Stargate Universe, the lead scientist, Dr. Nicholas Rush, hoped to use Shor's algorithm to crack Destinys master code.

Shor's algorithm was also a correct answer to a question in a Physics Bowl competition in the episode "The Bat Jar Conjecture" of the TV series The Big Bang Theory.

Theoretical computer science

While formal algorithms have existed for millennia (Euclid's algorithm for determining the greatest common divisor of two numbers is still used in computation), it was not until 1936 that Alan Turing, Alonzo Church and Stephen Kleene formalized the definition of an algorithm in terms of computation.

Visibility graph

Therefore, the Euclidean shortest path problem may be decomposed into two simpler subproblems: constructing the visibility graph, and applying a shortest path algorithm such as Dijkstra's algorithm to the graph.
