**Dynamic Programming Father**

Richard Ernest Bellman was born August 26, 1920-the first in New York (New York City) in a Jewish family with Polish and Russian roots. His mother`s name was Pearl Sufyan and his father John James Bellman was the owner of a small grocery store on Bergen Street, near Prospect Park in Brooklyn (Prospect Park, Brooklyn).

Richard attended Abraham Lincoln High School. He studied mathematics at Brooklyn College (Brooklyn College), where in 1941 received a bachelor`s degree. Then Bellman received a master`s degree from the University of Wisconsin in Madison (University of Wisconsin-Madison). During World War II he worked in theoretical physics at Los Alamos (Los Alamos). In 1946 Bellman became a doctor of philosophy at Princeton University (Princeton University).

Since 1949, Bellman worked as a researcher for the RAND Corporation, and it was then that he developed dynamic programming - a way of solving complex problems by breaking them down into simpler subtasks. Later in his life, Richard started to attach special importance to biology and medicine, which are defined as `the new field of modern nauki`. In 1967, he became the founder and editor of the journal `Mathematical Biosciences`, who specialized in the publication of applied research in mathematics for medical and biological purposes.

In 1973 Bellman was diagnosed with brain tumor `mozga`. Education has been removed, but due to complications, Richard left with severe disabilities. He was a professor at the University of Southern California (University of Southern California), a member of the American Academy of Arts and Sciences (American Academy of Arts and Sciences) in 1975, the National Academy of Engineering Sciences (National Academy of Engineering) in 1977 and the National Academy of Sciences (National Academy of Sciences) in 1983.

Bellman was awarded Medals of Honor of the Institute of Electrical and Electronics Engineers (IEEE) in 1979, `for his contribution to the theory of decision-making processes, and systems management theory, in particular, for the creation and application of dynamic programmirovaniya`. The key of his work was `equation Bellmana` or as it is called, the dynamic programming equation.

This equation is a sufficient condition for optimality, associated with mathematical optimization method known as dynamic programming. Almost any problem that can be solved by using the optimal control theory, we can find a solution by analyzing the corresponding Bellman equation. Bellman equation for the first time has been applied to management theory, multidisciplinary engineering and mathematics, as well as to other topics in the field of applied mathematics. Subsequently, the Bellman equation has become an important tool in economic theory.

The Hamilton-Jacobi-Bellman is central to the theory of optimal control. The solution of this differential equation in partial derivatives of the function is `znacheniya` giving optimum value to the controlled dynamic system, where the set value function.

Bellman-Ford algorithm, sometimes referred to as labels correction algorithm, search algorithm is the shortest path in a weighted graph, in this case allowed the ribs with negative weight. For graphs without edges of negative weight is usually used Dijkstra`s algorithm.

Richard E. Bellman died March 19, 1984 th, in Los Angeles, California (Los Angeles, California).
