1. In programming and mathematics:
* Iteration refers to the repeated execution of a set of instructions or a process. It's a key concept in programming loops, where a block of code is run multiple times, often with a change in some variable each time. This is used for tasks like:
* Processing a list of items one by one.
* Repeating a calculation until a certain condition is met.
* Simulating a process over time.
2. In design and development:
* Iteration refers to a cycle of development and improvement. It's common in product design, software engineering, and other fields. It involves:
* Planning and designing: Defining the problem and creating initial ideas.
* Building and testing: Developing a prototype or initial version, and testing it thoroughly.
* Evaluating and refining: Analyzing the results of testing, and making adjustments to improve the product or process.
* Repetition: Going through the cycle multiple times to make continual improvements.
3. In general usage:
* Iteration can simply mean repetition or recurrence. For example, "The author's works are full of iterations of the same themes."
In summary:
* Iteration is a powerful tool for solving problems and creating better solutions.
* It involves repeating a process to refine and improve the results.
Examples:
* Programming: A loop that iterates through a list of numbers and adds them together.
* Design: A design team that iterates on a website design multiple times, testing different layouts and features.
* General: The repeated appearance of a particular motif in a piece of art.
