What is the Adaptive Gradient Algorithm? In the field of deep learning optimization, adaptive gradient algorithms have become the preferred method for training neural networks. Unlike traditional gradient descent methods that use a uniform learning rate, adaptive algorithms assign different learning rates to each parameter, making the optimization process more efficient and stable. The core … Read more

In PCB manufacturing, the occurrence of voids in small diameter through-hole copper plating is indeed a troublesome issue, as it directly affects the reliability of the circuit and the yield of the product. This is often the result of multiple factors working together. The table below summarizes the common causes of copper plating voids and … Read more
With the continuous evolution of System-on-Chip (SoC) devices, modern electronic systems have gained unprecedented computing power while also presenting increasingly complex power distribution challenges. Especially in the context of companies striving to accelerate time-to-market and control costs, optimizing the Power Delivery Network (PDN) has become a key factor in successful product development. Author Zach Caprai … Read more
LLVM Ecosystem Pulse The LLVM ecosystem is evolving comprehensively at an unprecedented speed. This week, we not only witnessed the vigorous development of community activities but also observed fundamental discussions on the safety of the C language, instruction-level support for emerging hardware like RISC-V, and the redesign of internal optimization passes. What do these seemingly … Read more
Welcome to Ethan’s Air Garden. This is dedicated to creating a computer technology column that can be read during commutes, meals, or before bed, which is both accessible and in-depth. At CppCon 2017, Carl Cook delivered a talk titled “When a Microsecond Is an Eternity: High Performance Trading Systems in C++”. This article records the … Read more
Basics of Locks Locks are the core synchronization primitives in C++ concurrent programming, used to protect access to shared resources, ranging from simple variables to complex code segments. The C++11 standard library provides two core types of locks: mutex: an exclusive mutex, allowing only one thread to hold it at a time. shared_mutex: a shared-exclusive … Read more
1Main Content This program uses an adaptive genetic algorithm to optimize the configuration of distributed power sources, with the sum of investment operating costs, network loss costs, electricity purchase costs, and carbon emission costs as the optimization objective. The power flow calculation is performed using the forward-backward method. The program not only reproduces the 33-node … Read more

In the Linux kernel source code, the keywords likely and unlikely are frequently encountered. Upon examining the source code, it turns out that these two keywords are macros defined in the include/linux/compiler.h file of the kernel source (specifically in linux-3.11.0-rc1): Since CONFIG_PROFILE_ALL_BRANCHES is not defined, the definitions of the two macros are as follows: # … Read more
