The four symbols I used today during the lab were: cd (change directory), cal ( calender), date (show the date and time), and exit (to log off). The only noticeable difference between DOS, Windows, and Unix is DOS uses all caps.
As a definition, “A model is used for any complete and consistent set of verbal arguments, mathematical equations or computational rules which are thought to correspond to some observable entity in the world” (Lecture Notes). The best way to represent a model is through its prototype or best example of something. The process of modeling includes somewhat a process of steps. First one must experience and observe what’s being modeled and then reflect on it. What is its purpose? Then you come up with a formula and hypothesize or suggest an estimated guess to the question. And finally you experiment. You test what you hypothesized and look deeper and analyze your information. Fibonacci was the first one to propose a model. He did this through his numbers. A sample of his work includes the basics: B-> A, and A-> BA. The numbers are used to formulize and model many different things. Another form of modeling includes the branching L-systems. This can be used to model branches for example by adding more and more curved lines or +[F’s]. These systems were proposed to study biological development. Moving on from the Fibonacci Model and the L-system, things are also recorded and stored as and by vectors. Vectors are used as a representation for the goods and services for personal use. I found the ant colony clean up to be pretty interesting. It is said in the notes that in order to build and run a successful colony for ants, they must pick up a found dead ant, and drop them where there are more dead ants. This and the ant-inspired robots eventually result in clustering. Just as we do as a population, we follow the pack and almost become influenced by others and there train of thoughts, almost to believe that one knows better than you.
