Analysis of algorithms, typically using concepts like time complexity, can be used to get an estimate of the running time as a function of the size of the input data. The result is normally expressed using Big O notation. This is useful for comparing algorithms, especially when a large amount of data is to be processed.
Information flow of Reduce operation performed on three nodes. f is the associative operator and α is the result of the reduction. The reduce pattern [4] is used to collect data or partial results from different processing units and to combine them into a global result by a chosen operator.

A representation of the relationships between several important complexity classes. In computational complexity theory, a complexity class is a set of computational problems "of related resource-based complexity". [1] The two most commonly analyzed resources are time and memory.
Therefore, the time complexity, generally called bit complexity in this context, may be much larger than the arithmetic complexity. For example, the arithmetic complexity of the computation of the determinant of a n × n integer matrix is O ( n 3 ) {\displaystyle O(n^{3})} for the usual algorithms ( Gaussian elimination ).
Richard Blondel, co-author of the paper that originally published the Louvain method, seems to support this notion, [6] but other sources claim the time complexity is "essentially linear in the number of links in the graph," [7] meaning the time complexity would instead be (), where m is the number of edges in the graph. Unfortunately, no ...
Here, complexity refers to the time complexity of performing computations on a multitape Turing machine. [1] See big O notation for an explanation of the notation used. Note: Due to the variety of multiplication algorithms, () below stands in for the complexity of the chosen multiplication algorithm.
This operation has linear time complexity. In particular, initializing a disjoint-set forest with n nodes requires O(n) time. Lack of a parent assigned to the node implies that the node is not present in the forest. In practice, MakeSet must be preceded by an operation that allocates memory to hold x.
