Parallelization

Definition

Parallelization refers to the process of dividing a computational task into smaller sub-tasks that can be executed simultaneously across multiple processors or cores. This technique enhances efficiency and reduces the overall computation time, making it particularly valuable in optimization algorithms that require extensive calculations, such as those based on swarm intelligence principles.
