This module explains Min-Max and the Alpha-Beta algorithm for game playing. Its programming topics include C++ 11 Move semantics and a detailed example 

a matter of familiarizing yourself with the features they introduce (e.g., auto type declarations, move semantics, lambda expressions, and concurrency support).

April 12, 2014 (and then some) • The genesis of move semantics Move semantics is about transferring resources rather than copying them when nobody needs the source value anymore. In C++03, objects are often copied, only to be destroyed or assigned-over before any code uses the value again. 2012-11-20 · Lesson #5: Move Semantics Returning large objects from functions. With C++11 move semantics, we can simply return by value. As all of the STL Passing objects to functions efficiently. Consider the case where we have a vector of value objects. In old C++, adding Understanding move semantics.

[MS]:RU will continue to evolve in virtual space over … 2021-03-16 Copy versus move semantic: The differences between the copy and move semantic are huge. That holds in particular true for the associative containers. std::string: The std::string on Linux behaves strange. At one hand, copying is very fast; on the other hand, moving is only 16 times faster than copying.

So, what is move semantics? Move semantics makes it possible for compiler to replace expensive copying operations with less expensive moves. In instead of constructing/assigning an object by a deep copy, you can do it by move constructor or move assignment operators.

Se hela listan på internalpointers.com Se hela listan på cprogramming.com 2020-02-17 · C++ “move” semantics are simple, and unchanged since C++11. But they are still widely misunderstood, sometimes because of unclear teaching and sometimes because of a desire to view move as something else instead of what it is. This post is an attempt to shed light on that situation. Many components of the standard library implement move semantics, allowing to transfer ownership of the assets and properties of an object directly without having to copy them when the argument is an rvalue. Although note that -in the standard library- moving implies that the moved-from object is left in a valid but unspecified state. // explicit move (not going to use the variable 'str' after the create call) string str("Checkerboard"); TextureHandle htex = CreateTexture(128, 128, A8R8G8B8, std::move(str)); or // explicitly make a copy and pass the temporary of the copy down // since we need to use str again for some reason string str("Checkerboard"); TextureHandle htex = CreateTexture(128, 128, A8R8G8B8, string(str)); Move semantics is moving ownership of objects around and this includes concepts of move constructor.

Move semantics provide a way for the contents of objects to be 'moved' between objects, rather than copied, thus significantly changing the way we design+code C++ by allowing things like return by value to be used a lot more often. Move semantics solve a couple of common issues with old C++ … Returning large objects from functions

Not only is this much faster, it uses half the memory as there is no point during the process where each element has a duplicate data buffer.
