Study Notes
Algorithms, Explained: From Breadth-First Searches to Dynamic Programming
Algorithms play a crucial role in the field of computer science, providing solutions to various types of problems encountered during day-to-day activities. They assist in structuring, arranging, and manipulating information to achieve desired outcomes. Some popular types of algorithms include sorting algorithms, search algorithms, graph algorithms, greedy algorithms, and dynamic programming algorithms.
Sorting Algorithms
Sorting algorithms are designed to arrange elements in a particular order, typically ascending or descending. One of the most commonly used sorting algorithms is quicksort, which utilizes divide-and-conquer techniques to generate optimal partitions. Another popular choice is merge sort, which employs a stepwise process involving merge operations to sort larger data sets.
Search Algorithms
Search algorithms are responsible for identifying specific elements within unordered collections. One basic search strategy is linear search, which scans each element sequentially until a match is found. Alternatively, binary search narrows down the search area by repeatedly dividing the dataset in half, reducing the number of comparisons needed.
Graph Algorithms
Graph algorithms focus on navigating graph structures, which can be represented by directed or undirected connections between vertices. Popular graph algorithms include breadth-first search (BFS) and depth-first search (DFS). Both methods traverse the graph, exploring nodes and edges, but differ in their exploration strategies.
Greedy Algorithms
Greedy algorithms prioritize immediate gains, attempting to maximize profits by selecting the best option available at any given moment. An example of a greedy algorithm is the coin changer problem, which assigns coins to fill the remaining gap between the total sum and the coin denominations available.
Dynamic Programming
Dynamic programming breaks down complex problems into smaller, more manageable subproblems. This technique enables the calculation of optimal solutions using previously calculated results, avoiding unnecessary repetition. Applications of dynamic programming include the shortest path problem, which finds the shortest route between two points in a graph, and the knapsack problem, which involves filling a container with items of varying sizes and values.
