Algorithms and programming are the third Big Idea of Computer Science Principles. Two topics related to this Idea are developing algorithms and simulations.
Developing Algorithms
Algorithms have three main types: Sequence, Selection, and Iteration. When developing an algorithm, programmers must determine which ones they need to use and which ones they do not. The most advanced programs will use all three of them. Programmers must also test their algorithms thoroughly to make sure that they all work properly.
Simulations
Whenever you look at the weather and see the rain forecast, chances are you are looking at a simulation. Simulations are advanced algorithms used to experiment when actually doing the experiment would be too expensive, too dangerous, or impossible, such as the weather simulations. This can help us find out details about things that we would not be able to find out otherwise, like a simulation of an extinct animal, or increase the safety of people, like simulating a car crash in a new car model.
Relation to Computer Science
Algorithms are incredibly important to Computer Science, as everything using input or output is almost guaranteed to use some sort of algorithm. Algorithms also exist in every computing innovation, as every computing innovation needs to use an algorithm to have input and output, and to collect and store data.
