Bellman Equation
A Bellman equation, named after Richard E. Bellman, is a necessary condition for optimality associated with the mathematical optimization method known as dynamic programming. It writes the "value" of a decision problem at a certain point in time in terms of the payoff from some initial choices and the "value" of the remaining decision problem that results from those initial choices. This breaks a dynamic optimization problem into a sequence of simpler subproblems, as Bellman's “principle of optimality" prescribes. The equation applies to algebraic structures with a total ordering; for algebraic structures with a partial ordering, the generic Bellman's equation can be used. The Bellman equation was first applied to engineering control theory and to other topics in applied mathematics, and subsequently became an important tool in economic theory; though the basic concepts of dynamic programming are prefigured in John von Neumann and Oskar Morgenstern's '' Theory of Games and Econ ...

Bellman Joke
The Bellman joke is a type of simple joke cycle popular among Swedish schoolchildren, always including a person named Bellman as the main character. The jokes first became popular in the 19th century, and were originally inspired by the life of the poet and composer Carl Michael Bellman. The first known Bellman joke appears in the preface to an 1835 collection of Bellman's works, in which the publisher reprints an 1808 letter from a contemporary of Bellman, containing the following anecdote. 19th-century Bellman jokes tended to focus on C. M. Bellman's life at court, and often contained sexual humour. Since then, however, the Bellman character of the jokes has changed into a generic Swede, rather than the historical figure. The shift from jokes told by adults to jokes told mainly by young schoolchildren up to 10 years of age probably happened in the first half of the 20th century. The modern versions of the Bellman jokes often include Bellman and two other characters of differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bellman–Ford Algorithm
The Bellman–Ford algorithm is an algorithm that computes shortest paths from a single source vertex to all of the other vertices in a weighted digraph. It is slower than Dijkstra's algorithm for the same problem, but more versatile, as it is capable of handling graphs in which some of the edge weights are negative numbers. The algorithm was first proposed by , but is instead named after Richard Bellman and Lester Ford Jr., who published it in 1958 and 1956, respectively. Edward F. Moore also published a variation of the algorithm in 1959, and for this reason it is also sometimes called the Bellman–Ford–Moore algorithm. Negative edge weights are found in various applications of graphs, hence the usefulness of this algorithm. If a graph contains a "negative cycle" (i.e. a cycle whose edges sum to a negative value) that is reachable from the source, then there is no ''cheapest'' path: any path that has a point on the negative cycle can be made cheaper by one more walk ...

Hamilton–Jacobi–Bellman Equation
In optimal control theory, the Hamilton-Jacobi-Bellman (HJB) equation gives a necessary and sufficient condition for optimality of a control with respect to a loss function. It is, in general, a nonlinear partial differential equation in the value function, which means its solution the value function itself. Once this solution is known, it can be used to obtain the optimal control by taking the maximizer (or minimizer) of the Hamiltonian involved in the HJB equation. The equation is a result of the theory of dynamic programming which was pioneered in the 1950s by Richard Bellman and coworkers. The connection to the Hamilton–Jacobi equation from classical physics was first drawn by Rudolf Kálmán. In discrete-time problems, the corresponding difference equation is usually referred to as the Bellman equation. While classical variational problems, such as the brachistochrone problem, can be solved using the Hamilton–Jacobi–Bellman equation, the method can be applied to a ...

The Hunting Of The Snark
''The Hunting of the Snark'', subtitled ''An Agony in 8 Fits'', is a poem by the English writer Lewis Carroll. It is typically categorised as a nonsense poem. Written between 1874 and 1876, it borrows the setting, some creatures, and eight portmanteau words from Carroll's earlier poem "Jabberwocky" in his children's novel ''Through the Looking-Glass'' (1871). The narrative follows a crew of ten trying to hunt the Snark, a creature which may turn out to be a highly dangerous ''Boojum''. The only crewmember to find the Snark quietly vanishes, leading the narrator to explain that the Snark was a Boojum after all. The poem is dedicated to young Gertrude Chataway, whom Carroll met at the English seaside town Sandown in the Isle of Wight in 1875. Included with many copies of the first edition of the poem was Carroll's religious tract, ''An Easter Greeting to Every Child Who Loves "Alice"''. ''The Hunting of the Snark'' was published by Macmillan in the United Kingdom in March 1876 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bellman Prize
The Bellman Prize ( sv, Bellmanpriset) is a literature prize for "an outstanding Swedish poet" awarded yearly by the Swedish Academy ( sv, Svenska Akademien) The prize was first established by Anders Zorn (1860-1920) and his wife Emma Lamm (1860–1942). In 1920, they had established the Emma and Anders Zorn's Donation Fund Foundation ( sv, Stiftelsen Emma och Anders Zorns donationsfond). A donation from the foundation was used to fund the Swedish Academy-Bellman Prize.

Town Crier
A town crier, also called a bellman, is an officer of a royal court or public authority who makes public pronouncements as required. Duties and functions The town crier was used to make public announcements in the streets. Criers often dress elaborately, by a tradition dating to the 18th century, in a red and gold coat, white breeches, black boots and a tricorne hat. In English-speaking countries, they carried a handbell to attract people's attention, as they shouted the words "Oyez, Oyez, Oyez!" before making their announcements. The word "Oyez" means "hear ye," which is a call for silence and attention. ''Oyez'' derives from the Anglo-Norman word for ''listen'' (modern French, ''oyez'', infinitive, ''ouïr'', but has been largely replaced by the verb ''écouter''). The proclamations book in Chester from the early 19th century records this as "O Yes, O Yes!"

Bellman (diving)
A diving team is a group of people who work together to conduct a diving operation. A characteristic of professional diving is the specification for minimum personnel for the diving support team. This typically specifies the minimum number of support team members and their appointed responsibilities in the team based on the circumstances and mode of diving, and the minimum qualifications for specified members of the diving support team. The minimum team requirements may be specified by regulation or code of practice. Some specific appointments within a professional dive team have defined competences and registration may be required. There is considerable difference in the diving procedures of professional divers, where a diving team with formally appointed members in specific roles and with recognised competence is required by law, and recreational diving, where in most jurisdictions the diver is not constrained by specific laws, and in many cases is not required to provide any ...
