Theoretical analysis of time efficiency Time efficiency is analyzed by determining the number of repetitions of the basic operation as a function of input size • Basic operation: the operation that contributes most towards the running time of the algorithm T(n) ≈ copC(n) running time execution time for basic operation Number of times basic operation is executed input size … What is Algorithm? When we analyze algorithms, we should employ mathematical techniques that analyze algorithms independently of specific implementations, computers, or data. The running time of an algorithm is influenced by several factors: • Speed of the machine running the program • … How fast the function that characterizes the running time grows with the input size. Many of them are also animated.

Algorithm • Algorithm is step by step procedure to solve any problem. Analyzing / Judgment of the Algorithm • An algorithm can be written in different ways for solving a single problem. Amortized Analysis. It was supposed to recognize mental commands, as well as detect artifacts in the form of blinking and change the direction of the robot’s movement. The Design and Analysis of Algorithms. Use pseudocode to clarify sufficiently tricky details of … To perform the asymptotic analysis " We find the worst-case number of primitive operations executed as a function of the input size ALGORITHM. It is also one that is familiar to most students. • Performance of an algorithm is a process of making evaluative judgment about algorithms. • Performance of an algorithm means predicting the resources which are required to an algorithm to perform its task. • That means when we have multiple algorithms to solve a problem, we need to select a suitable algorithm to solve that problem. Running Time (§3.1) Most algorithms transform input objects into output objects.

- An algorithm is a sequence of unambiguous instructions for solving a problem, i.e., for obtaining a required output for any legitimate input in a finite amount of time. Coming up ; Asymptotic performance, Insertion Sort ; A formal introduction to asymptotic notation (Chap 2.1-2.2, Chap 3.1) 3 Asymptotic performance In analysis of algorithms, we care most about asymptotic performance. Study Resources. • Any analysis must be independent of specific data. 5. CENG 213 Data Structures 5 Analysis of Algorithms • When we analyze algorithms, we should employ mathematical techniques that analyze algorithms independently of specific implementations, computers, or data. Analysis of Algorithms. An algorithm can be analyzed in terms of time efficiency or space utilization. Algorithm • Algorithm is step by step procedure to solve any problem.
