Design and Analysis of Algorithm Tutorial Last Updated : 23 Jul, 2025 Comments Improve Suggest changes 14 Likes Like Report Design and Analysis of Algorithms is a fundamental area in computer science that focuses on understanding how to solve problems efficiently using algorithms. It is about designing algorithms that are not only correct but also optimal, taking into account factors like time and space efficiency.Algorithm design is the process of developing a step-by-step procedure to solve a specific problem. Various techniques can be used for designing algorithms, including:Divide and Conquer: Divides the problem into smaller sub-problems, solves each sub-problem independently, and combines the results. Example: Merge Sort, Quick Sort.Greedy Algorithms: Focuses on making the locally optimal choice at each stage in the hope of finding the global optimum. Example: Huffman Encoding.Dynamic Programming: Breaks down a problem into simpler overlapping sub-problems and solves each sub-problem only once, storing the results. Example: Fibonacci Sequence, Knapsack Problem.Backtracking: Solves problems incrementally and abandons solutions that are not viable. Example: Solving a Sudoku puzzle.DAAIntroduction to Algorithm Analysis AlgorithmsImportance of AnalysisOrder of GrowthAsymptotic AnalysisWorst, Average and Best Cases of AlgorithmsBig-O NotationTheta - Θ NotationBig – Ω (Big- Omega) NotationTime ComplexitySpace ComplexityAlgorithms Design TechniquesIterative Algorithms Linear Search AlgorithmInsertion Sort AlgorithmBubble Sort AlgorithmSelection Sort AlgorithmDivide and Conquer Algorithms Introduction to Divide and Conquer AlgorithmMax & MinBinary Search AlgorithmMerge SortQuick SortStrassen’s Matrix MultiplicationKaratsuba algorithm for fast multiplicationMaster theorem for divide and conquer recurrencesRecursion Tree methodGreedy Algorithms Introduction to Greedy AlgorithmGreedy Algorithms General StructureFractional KnapsackJob Sequencing ProblemOptimal File Merge PatternsHuffman CodingMinimum Spanning Tree Dijkstra’s AlgorithmDynamic Programmingtroduction to DPTabulation vs MemoizationSteps to solve a DP ProblemMultistage Graph0/1 Knapsack ProblemTravelling Salesman ProblemLongest Common Subsequence (LCS)Floyd Warshall AlgorithmBellman–Ford AlgorithmMatrix Chain MultiplicationSubset Sum ProblemGraph AlgorithmsGraph and its representationsTypes of GraphsDFS for a GraphBFS for a GraphParenthesis TheoremHeap AlgorithmsBinary HeapBuilding Heap from ArrayHeap SortBacktracking & Branch-BoundIntroduction to BacktrackingBacktracking vs RecursionIntroduction to Branch and BoundBacktracking vs Branch and BoundN Queen ProblemHamiltonian CyclePermutations of a StringNP Completeness Introduction to NP-Complete Complexity ClassesP vs NP ProblemsNP-Hard ClassDifference between NP hard and NP complete Create Quiz Comment U ujjwalroq0 Follow 14 Improve U ujjwalroq0 Follow 14 Improve Article Tags : DSA Explore DSA FundamentalsLogic Building Problems 2 min read Analysis of Algorithms 1 min read Data StructuresArray Data Structure 3 min read String in Data Structure 2 min read Hashing in Data Structure 2 min read Linked List Data Structure 2 min read Stack Data Structure 2 min read Queue Data Structure 2 min read Tree Data Structure 2 min read Graph Data Structure 3 min read Trie Data Structure 15+ min read AlgorithmsSearching Algorithms 2 min read Sorting Algorithms 3 min read Introduction to Recursion 15 min read Greedy Algorithms 3 min read Graph Algorithms 3 min read Dynamic Programming or DP 3 min read Bitwise Algorithms 4 min read AdvancedSegment Tree 2 min read Binary Indexed Tree or Fenwick Tree 15 min read Square Root (Sqrt) Decomposition Algorithm 15+ min read Binary Lifting 15+ min read Geometry 2 min read Interview PreparationInterview Corner 3 min read GfG160 3 min read Practice ProblemGeeksforGeeks Practice - Leading Online Coding Platform 1 min read Problem of The Day - Develop the Habit of Coding 5 min read Like
