How to implement chicken flock algorithm in Python

Algorithm Introduction Chicken Swarm Optimization, abbreviated as CSO (ChickenSwarmOptimization), although it has a background in so-called bionics, is essentially a variant of the particle swarm algorithm. To put it simply, a particle swarm is a group of particles. Each particle has its own position and speed, and each particle is attracted by the best particle. Apart from these two rules, the particles are completely equal to each other. Except for position and speed, they are completely equal. Of course, the particle swarm algorithm itself also has a background in bionics. It is said that it was inspired by a flock of birds looking for food. This is of course not important. It is nothing more than a group of equal particles turning into a group of equal birds. The chicken flock algorithm adds different identity characteristics to these particles, or these birds,

How to build a decision tree in Python

Decision Trees Decision trees are an integral part of today's most powerful supervised learning methods. A decision tree is basically a flowchart of a binary tree where each node splits a set of observations based on some characteristic variable. The goal of a decision tree is to separate data into groups such that every element in a group belongs to the same category. Decision trees can also be used to approximate continuous target variables. In this case, the tree will be split such that each group has the smallest mean squared error. An important property of decision trees is that they are easily interpretable. You don't need to be familiar with machine learning techniques at all to understand what decision trees are doing. Decision tree diagrams are easy to interpret. Pros and Cons The advantage of the decision tree approach is that decision trees generate understandable rules. Decision trees perform classification without requiring extensive calculations. decision making
