Study Notes
Chapter 1: Introduction to Algorithm Design
- Algorithms are finite sequences of instructions that can be performed with a finite amount of effort in a finite length of time.
-
Key questions regarding algorithms:
- Specification: What is the algorithm supposed to do?
- Verification: Does the algorithm really do what it is supposed to do?
- Performance analysis: How efficiently does the algorithm work?
- Data structures are ways of organizing data for particular types of operations. They can be represented by abstract mathematical models called abstract data types.
- Design patterns describe the design of algorithms, providing general structures for algorithms.
- Imperative Programming describes computation in terms of instructions that change the program/data state.
- Declarative Programming specifies what the program should accomplish without describing how to do it. These notes primarily focus on developing algorithms for imperative programming.
- Pseudocode is a way to write algorithms in a format that bridges between English and programming code but is not runnable due to missing details.
Chapter 2: Elementary Data Structures
- Arrays are ordered collections of elements, accessed using their index (position).
- Index: The position of an element in an array.
- Size: The number of elements in an array.
- The index starts from 0 (not 1) in most computer science applications.
-
Example: The array
a = [1, 4, 17, 3, 90, 79, 4, 6, 81]
has 9 elements and its size is 9. The elementa[8]
is equal to 81. -
Loops: Used to repeat a process a certain number of times.
-
For Loop: Typically written as "for i = 1,...,N, do something" in pseudocode, or "for( i = 0 ; i < N ; i++ ) { // do something }" in programming languages.
- Used for iterating over an index to perform the same operation on each element in the array.
-
For Loop: Typically written as "for i = 1,...,N, do something" in pseudocode, or "for( i = 0 ; i < N ; i++ ) { // do something }" in programming languages.
Chapter 5: Computational Efficiency
- Efficiency of an algorithm refers to the resources it requires, including execution time and memory usage.
- Problem instance size: The size of the input data.
- The choice of data representation and algorithm details affect efficiency.
