Time complexity of selection sort?
Merge sort (or mergesort) is an algorithm. Algorithms do not have running times since running times are determined by the algorithm's performance/complexity, the programming language used to implement the algorithm and the hardware the implementation is executed upon. When we speak of algorithm running times we are actually referring to the algorithm's performance/complexity, which is typically notated using Big O notation. Mergesort has a worst, best and average case performance of O(n log n). The natural variant which exploits already-sorted runs has a best case performance of O(n). The worst case space complexity is O(n) auxiliary.
What is the worst case and best case of bubble sort?
There is no worst case for merge sort. Each sort takes the same amount of steps, so the worst case is equal to the average case and best case. In each case it has a complexity of O( N * log(N) ).
What is the big-O worst-case complexity of this algorithm?
Can't say without some detail about the algorithm in question.
What is the worst case and best case time complexity of heapsort?
The best and worst case time complexity for heapsort is O(n log n).
What is time complexity of genetic algorithm?
The answer to this question depends on several things, the most important of which is the fitness evaluation. I'm going to ignore evaluation- you must determine this for yourself based on your application. Some of the things the effect the time complexity are:the data structures used to represent the individuals and the population, the genetic operators used, and the implementation of the genetic operators. Roulette wheel selection, for example, can be anywhere from O(n^2) when done naively, to O(log(n)), or even O(n) using something like Vose Alias Algorithm. The simplest case- roulette wheel selection, point mutation, and one point crossover with both individuals and populations represented by fixed length vectors- has time complexity O(gens * (mut + cross + select)) where gens is the number of generations, mut is the complexity of point mutation (n*m with n the size of the population and m the size of the individuals), cross the time complexity of crossover (n*m again), and select the time complexity of selection (n in the case of an efficiently done roulette wheel). Therefore, the time complexity of a simple Genetic Algorithm is O(gens*n*m) as this is the dominating term. I'm sure a much better explanation can be found in the literature.
What is the memory complexity of quick sort algorithm?
The memory complexity of the quick sort algorithm is O(log n) in the best case and O(n) in the worst case.
What is the best case scenario for the bubble sort algorithm in terms of time complexity?
The best case scenario for the bubble sort algorithm is when the list is already sorted. In this case, the time complexity is O(n), where n is the number of elements in the list.

What is the best and worst case time complexity of the Bubble Sort algorithm?
The best-case time complexity of the Bubble Sort algorithm is O(n), where n is the number of elements in the array. This occurs when the array is already sorted. The worst-case time complexity is O(n2), which happens when the array is sorted in reverse order.
What is the time complexity of quicksort algorithm?
The time complexity of the quicksort algorithm is O(n log n) in the average case and O(n2) in the worst case.
What is the average case time complexity of the algorithm?
The average case time complexity of an algorithm is the amount of time it takes to run on average, based on the input data. It is a measure of how efficient the algorithm is in terms of time.
What is the average case complexity of the algorithm being used for this specific problem?
The average case complexity of an algorithm refers to the expected time or space required to solve a problem under typical conditions. It is important to analyze this complexity to understand how efficient the algorithm is in practice.
What is the time complexity of quick sort algorithm?
The time complexity of the quick sort algorithm is O(n log n) in the average case and O(n2) in the worst case.
