The name comes from the way that RCU is used to update a linked structure in place. A thread wishing to do this uses the following steps: create a new structure, copy the data from the old structure into the new one, and save a pointer to the old structure, modify the new, copied, structure, update the global pointer to refer to the new structure,
In computer programming, create, read, update, and delete (CRUD) are the four basic operations (actions) of persistent storage. [1] CRUD is also sometimes used to describe user interface conventions that facilitate viewing, searching, and changing information using computer-based forms and reports .
To calculate the net force on a particular body, the nodes of the tree are traversed, starting from the root. If the center of mass of an internal node is sufficiently far from the body, the bodies contained in that part of the tree are treated as a single particle whose position and mass is respectively the center of mass and total mass of the internal node.
Update crossbar value ′ (,) = (,) + (′). The term “secondary reinforcement” is borrowed from animal learning theory, to model state values via backpropagation: the state value (′) of the consequence situation is backpropagated to the previously encountered situations. CAA computes state values vertically and actions ...
In mathematical optimization, the revised simplex method is a variant of George Dantzig's simplex method for linear programming.. The revised simplex method is mathematically equivalent to the standard simplex method but differs in implementation.
The geometric interpretation of Newton's method is that at each iteration, it amounts to the fitting of a parabola to the graph of () at the trial value , having the same slope and curvature as the graph at that point, and then proceeding to the maximum or minimum of that parabola (in higher dimensions, this may also be a saddle point), see below.
A Pascaline signed by Pascal in 1652 Top view and overview of the entire mechanism. This version of Pascaline was for accounting. [1]Pascaline (also known as the arithmetic machine or Pascal's calculator) is a mechanical calculator invented by Blaise Pascal in 1642.
