 ## What are they?
 
-Asymptotic Notations are languages that allow us to analyze an algorithm's running time by
-identifying its behavior as the input size for the algorithm increases. This is also known as
-an algorithm's growth rate. Does the algorithm suddenly become incredibly slow when the input
-size grows? Does it mostly maintain its quick run time as the input size increases?
-Asymptotic Notation gives us the ability to answer these questions.

 ## Are there alternatives to answering these questions?
 
-One way would be to count the number of primitive operations at different input sizes.
-Though this is a valid solution, the amount of work this takes for even simple algorithms
-does not justify its use.

-Another way is to physically measure the amount of time an algorithm takes to complete

-only be relative to the machine they were computed on) of this method is bound to
-environmental variables such as computer hardware specifications, processing power, etc.

 ## Types of Asymptotic Notation
 
-In the first section of this doc we described how an Asymptotic Notation identifies the
-behavior of an algorithm as the input size changes. Let us imagine an algorithm as a function
-f, n as the input size, and f(n) being the running time. So for a given algorithm f, with input
-size n you get some resultant run time f(n). This results in a graph where the Y axis is the
-runtime, X axis is the input size, and plot points are the resultants of the amount of time
-for a given input size.
-
-You can label a function, or algorithm, with an Asymptotic Notation in many different ways.
-Some examples are, you can describe an algorithm by its best case, worse case, or equivalent case.
-The most common is to analyze an algorithm by its worst case. You typically don't evaluate by best case because those conditions aren't what you're planning for. A very good example of this is sorting algorithms; specifically, adding elements to a tree structure. Best case for most algorithms could be as low as a single operation. However, in most cases, the element you're adding will need to be sorted appropriately through the tree, which could mean examining an entire branch. This is the worst case, and this is what we plan for.

-These are some basic function growth classifications used in various notations. The list starts at the slowest growing function (logarithmic, fastest execution time) and goes on to the fastest growing (exponential, slowest execution time).
