——————————————————————————————— In this tutorial we will understand the 3 different Asymptotic Time Complexity analysis of Algorithms namely –

Big Oh(O)

Big Omega(Ω)

Big Theta(θ)

We will understand each Complexity by taking its mathematical definition as well as example with graph.

Lastly we will understand its practical usage \u0026 understand why we really need 3 different time complexity measures.

Big O notation –

Big O notation specifically describes worst case scenario.

It represents the upper bound running time complexity of an algorithm.

Mathematically –

Let f and g be functions of n – where n is natural no denoting size or steps of the algorithm then –

f(n) = O(g(n))

IFF

f(n) less than or = c.g(n)

where n greater than = n0, c greater than 0, n0 greater than = 1

Big Omega notation –

Big Omega notation specifically describes best case scenario.

It represents the lower bound running time complexity of an algorithm.

Basically it tells you what is the fastest time/behavior in which the algorithm can run.

f(n) = Ω(g(n))

IFF

f(n) greater than or = c.g(n)

where n greater than = n0, c greater than 0, n0 greater than = 1

Big Theta (θ) notation –

Big Omega notation specifically describes average case scenario.

It represents the most realistic time complexity of an algorithm.

f(n) = θ(g(n))

IFF

c1.g(n) less than or = f(n) less than or = c2.g(n)

where n greater than = n0, c1,c2 greater than 0, n greater than = n0, n0 greater = 1

Big Ω – Best Case

Big O – Worst Case

Big θ – Average Case

For this algorithms video lesson, we explain and demonstrate the main asymptotic bounds associated with measuring algorithm performance: big O, big omega, and big theta. in algorithm analysis, we are more with how an algorithm scales than the exact time of execution. This is sometimes referred to as complexity analysis.
