"title" A Particle swarm optimization algorithm with multi-scale cooperative mutation (2010)"thesis author" Tao Ning, Liufurong, Christina, Dong Zhijing"Paper Link" Paper (14-pages)SummaryThis paper analyzes the influence of mutation operation on particle swarm optimization (PSO), proposes a new PSO algorithm with multi-scale cooperative mutation, aiming at the disadvantage of single mutation, slow converge

no improvement; 3. The optimal value of the problem is less than the given threshold value. Particle swarm (PSO) algorithm is the most popular evolutionary algorithm in recent years, which was first proposed by Kenned and Eberhart in 1995. The PSO algorithm is similar to other evolutionary algorithms, and uses the concept of "group" and "evolution" to realize the search of the optimal solution in complex space through collaboration and competition am

When I first considered paying in crypto currency, I looked at available solutions like stripe. I think the problem with stripe is that it only allows Bitcoin payments with a U.S. merchant account, so that's not a choice for me. In the Ethereum world, it looks worse. There are some newer services, but they all want to share the cake.So what do we need to build the Ethereum payment system from the beginning?

Ethereum represents one of the most interesting technological developments in the past few-years, taking the fundamental p Rinciples of a blockchain, and allowing executable "contracts" to be written. These contracts can is relatively simple but also incredibly powerful. This post'll walk you through setting up a development environment so can deploy and test your smart own CTS on the Ethereum test blockcha

[Ethereum Tutorial] How to create a private chain Introduction:This tutorial describes what to build a Ethereum private chain for development experiments The purpose of creating a private chain:The purpose of building a private chain is to facilitate the experiment on the chain. An experimental development on a public chain can leads to unnecessary waste of money. Because you need gas to does anything on t

Introduction to Mining The term mining is derived from the analogy between cryptocurrency and gold. Gold or precious metals are rare, and electronic tokens are also the only way to increase the total is to dig mine. So is Ethereum, and the only way to release it is to dig mine. But unlike other examples, mining is also a way to protect the network by creating, validating, distributing, and propagating chunks in the blockchain. Dig aether = Protect Ne

We ' re back on it in the Proof of Work difficulty spectrum, this time going through how Ethereum ' s difficulty Time. This is part 4.2 of the "Part 4 series" Where part 4.1 was about Bitcoin ' PoW difficulty, and the following 4.3 would be ab Out JBC ' s PoW difficulty. Tl;dr To calculate the difficulty for the next Ethereum blocks, you calculate the time it took to mine the previous blocks, and if That's

Docker service is a declarative, scalable, load-balanced application. Docker service is a user-oriented application, while Docker swarm is an IT-oriented node cluster. Docker service is often run on the basis of Docker swarm. Common commands for Docker service:Docker Service Create--name myservice-p 8080:8080--replicas 5 an_image Description, create a Docker service with 5 copiesDocker Service LS Docker
