Article Introduction：Summary of solutions to common compilation optimization problems in C++: When writing programs in C++, we often encounter some performance bottlenecks that affect the running efficiency of the program. In order to improve the execution efficiency of the code, we can use the compiler to optimize. This article will introduce some common compilation optimization problems and their solutions, and give specific code examples. 1. Loop optimization In C++, loops are an important part of the program. The code in the loop is executed many times, so the optimization of the loop has a great impact on the performance of the overall program. Expand

Article Introduction：Neural Radiation Field (NeRF) based purely on MLP often suffers from under-fitting in large-scale scene blur rendering due to limited model capacity. Recently, some researchers proposed to geographically divide the scene and use multiple sub-NeRFs to model each area separately. However, the problem caused by this is that as the scene gradually expands, the training cost becomes linear with the number of sub-NeRFs. expand. An alternative solution is to use a voxel feature grid representation, which is computationally efficient and scales naturally to large scenes with increasing grid resolution. However, feature meshes often only achieve suboptimal solutions due to fewer constraints, producing some noise artifacts in rendering, especially in areas with complex geometry and textures. In this article, researchers from the Chinese University of Hong Kong and Shanghai Artificial Intelligence

Article Introduction：1. What does it mean for the computer to sleep? Computer hibernation refers to turning off the computer when it is not in use. When the power is subsequently turned on, all work (including programs and documents that have not been saved or closed) will be restored to the state exactly when it was left. When the computer is in hibernation, the contents of the memory will be saved on the disk, and the monitor and hard disk will be turned off. This also saves power and reduces the loss of the computer. Generally speaking, it takes longer to bring the computer out of hibernation than from standby, but hibernation consumes less power. How to start hibernation (taking WIN10 as an example): 1. On the computer desktop, right-click the menu key in the lower left corner. 2. Find the shutdown or logout option and click it. 3. Click on sleep. expand
