Computational complexity is one of the measuring sticks we’re using to compare different solutions, in an attempt to decide which one is the better choice. What are we measuring ? The goal for us is to decide which solution is better. A more precise definition of the computational complexity of an algorithm is the concept of a cost function (step-counting function) — defined as a decidable relation between the objects to which the algorithm is applicable and the natural numbers, and which has a range of definition coinciding with the range of applicability of the algorithm. Computational complexity, roughly speaking how difficult a problem is to solve, has turned out to be an area of study that has revolutionised the way that we think about the world. Forget relativity, black holes and the origins of time; computing has provided us with an incredible perspective on the universe of what we can and cannot know. Some of the major threads are the Turing machine, complexity models, nondeterministic polynomial time (NP) and NP completeness, randomized computation, circuits, and proofs. In addition, there are single chapters that cover topics such as diagonalization, cryptography, quantum computation, decision trees, and communication theory. Lecture 23: Computational Complexity. Description: This lecture introduces computational complexity, including how most decision problems are uncomputable, hardness and completeness, and reductions. Introduction. The term “computational complexity” has two usages which must be distinguished. On the one hand, it refers to an algorithm. for solving instances of a problem: broadly stated, the computational complexity of an algorithm is a measure of how many steps the algorithm will require in the worst case for an instance or input of a given size. Know Thy Complexities! Hi there! This webpage covers the space and time Big-O complexities of common algorithms used in Computer Science. When preparing for technical interviews in the past, I found myself spending hours crawling the internet putting together the best, average, and worst case complexities for search and sorting algorithms so that I wouldn't be stumped when asked about them.

Computational complexity theory is the study of the complexity of problems – that is, the difficulty of solving them. Problems can be classified by complexity class according to the time it takes for an algorithm – usually a computer program – to solve them as a function of the problem size.
