The Big-O notation: the running time of an algorithm as a function of the size of its input. worst case estimate. asymptotic behavior. O(n2) means that the running time of the algorithm on an input of size n is limited by the quadratic function of n.
Designing better algorithms. Analyzing the asymptotic running time of algorithms is a useful way of thinking about algorithms that often leads to nonobvious improvements. Understanding. An analysis can tell us what parts of an algorithm are crucial for what kinds of inputs, and why.
4 Lecture 13: Dijkstra’s Algorithm. Running Time • Count operations on changeable priority queue Q, assuming it contains n items: Operation Time
For simplicity, we compute the running time of an algorithm as a function of the length of the string that represents the input. In worst-case analysis, we consider the longest running time of all inputs of a particular length (that is all we care about in this class)
This lecture introduces a single source shortest path algorithm that works for general graphs. The process, correctness, and running time of the Bellman-Ford algorithm is discussed. Instructor: Jason Ku

16 mar 2022 · A complete analysis of the running time of an algorithm involves the following steps: Implement the algorithm completely. Determine the time required for each basic operation. Identify unknown quantities that can be used to describe the frequency of execution of the basic operations. Develop a realistic model for the input to the program.
