Efficient Fibonacci (WIP)

Image
This was a little side thing I've been working on. I wanted to find a way to find a number (especially big ones) in the Fibonacci sequence without using recursion or memoization. After researching it a bit I came across this equation online. F(n) = ⌊Φⁿ/√5 + 1/2⌋,  with   Φ = (1+ √5 )/2 With this my program could find the right number from any position n  without resorting to make multiple recursion and having to find the Fibonacci of every number below n , effectively ( hopefully ) making it faster and more efficient.

Software Engineering: Petri Nets

Image
This'll be a sort of  abridged  summary of the topic, any more information you might need, I recommend you try the book (name in bottom of the post). The circles are states in the domain. With the arrows pointing to where the process is going And the thin rectangles the transitions between states  Petri Nets are basically a diagram to help us visualize the process and how it flows in a domain. In this chapter we talk about three types of representations: Condition Event Nets (CEN) Petri Nets (PTN) Colored Petri Nets (CPN) Condition Event Nets are the most basic type of Petri nets. A CEN consists of conditions (states), events (transitions) and links (arrows) from conditions to events and from events to conditions. Syntactically conditions are represented as circles, while events are represented as oblong, i.e., "thin", rectangles. Petri Nets  are pretty much the same as CENs but conditions are now called places and in those plac...

Software Engineering: Phenomena and Concepts

Image
This'll be a sort of  abridged  summary of the topic, any more information you might need, I recommend you try the book (name in bottom of the post). When talking about concepts  and phenomena  (in the context of the book) as follows: Phenomena -  It is what we refer to as Reality,  as in things we perceive in the real world, things that are concrete. Concepts  - More abstract, it is the idea  of a given phenomena. An example of this can be something like a Car. Phenomena: Automobile -> Concept: Car A car is a concept (an idea) of an automobile, where an automobile can be anything in the real word that serves that specific purpose. We can also take things a step further, with the type of entity that we use. Atomic Entities Compound Entities Atomic Entities: Individual entities, broken down to it's most basic representation. (For the purpose of the domain that you wish to represent) Example: Ch...
