What are the main differences between genetic algorithms (GA) and particle swarm optimization (PSO)?
What are the main differences between genetic algorithms (GA) and particle swarm optimization (PSO)?
- GA involves genetic operations like crossover and mutation, while PSO involves updating particle velocities based on the best fitness values.
- GA uses a population-based approach, while PSO uses a swarm-based approach. (correct)
- GA searches the solution space using velocity and position updates, while PSO searches for solutions by evolving a population of candidate solutions.
- GA focuses on finding optimal solutions through natural selection, while PSO focuses on optimization through simulating the social behavior of bird flocks.

Study Notes
Optimization Algorithms
- Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) are two distinct optimization techniques
- GA is a heuristic search algorithm inspired by Charles Darwin's theory of natural evolution, using processes like mutation, selection, and crossover to search for optimal solutions
- PSO is a population-based optimization algorithm that uses a swarm of particles to search for optimal solutions, inspired by the social behavior of bird flocking and fish schooling
Machine Learning
- Machine learning enables an intelligent system to improve its performance over time by learning from data and experiences
- Through machine learning, an intelligent system can adapt to new situations, improve its accuracy, and make better decisions
Neural Networks
- A neural network is a machine learning model inspired by the structure and function of the human brain
- Neural networks consist of interconnected nodes or "neurons" that process and transmit information
Human Brain Processing Power
- The human brain's processing power is attributed to its estimated 86 billion neurons, each connected to thousands of other neurons
- The human brain's neural network is thought to process information at a rate of exaflops (1 exaflop = 1 billion billion calculations per second)
Neuron Components
- A neuron consists of dendrites (receive signals), cell body (processes information), axon (transmits signals), and terminal buttons (release neurotransmitters)
- Neurotransmitters are chemical messengers that transmit signals from one neuron to another
