These algorithms are essential to every programmer's workflow.
Mickael Ruau's insight:
1. Dijkstra’s AlgorithmDijkstra’s algorithm finds the single shortest path in a graph from a source to all graph vertices.
2. Merge SortWe’ve got a couple of sorting algorithms on this list, and merge sort is one of the most important algorithms. It's an efficient sorting algorithm based on the Divide and Conquer programming technique. 3. QuicksortQuicksort is another sorting algorithm based on the Divide and Conquer programming technique. In this algorithm, an element is first chosen as the pivot, and the entire array is then partitioned around this pivot. 4. Depth First SearchDepth First Search (DFS) is one of the first graph algorithms taught to students. DFS is an efficient algorithm used to traverse or search a graph. It can also be modified to be used in tree traversal. Typical applications of the DFS traversal include topological sort, detecting cycles in a graph, pathfinding, and finding strongly connected components. 5. Breadth-First SearchBreadth-First Search (BFS) is also known as a level order traversal for trees. BFS works in O(V+E) similar to a DFS algorithm. However, BFS uses a queue instead of the stack. DFS dives into the graph, whereas BFS traverses the graph breadthwise. The BFS algorithm utilizes a queue to keep track of the vertices. Unvisited adjacent vertices are visited, marked, and queued. If the vertex doesn't have any adjacent vertice, then a vertice is removed from the queue and explored. BFS is commonly used in peer-to-peer networks, shortest path of an unweighted graph, and to find the minimum spanning tree. 6. Binary SearchBinary Search is a simple algorithm to find the required element in a sorted array. It works by repeatedly dividing the array in half. If the required element is smaller than the middlemost element, then the left side of the middle element is processed further; otherwise, the right side is halved and searched again. The process is repeated until the required element is found. The worst-case time complexity of binary search is O(logn) which makes it very efficient at searching linear arrays. 7. Minimum Spanning Tree AlgorithmsA minimum spanning tree (MST) of a graph has the minimum cost among all possible spanning trees. The cost of a spanning tree depends on the weight of its edges. It's important to note that there can be more than one minimum spanning tree. There are two main MST algorithms, namely Kruskal’s and Prim’s.
Minimum spanning tree algorithms are essential for cluster analysis, taxonomy, and broadcast networks.

Le fondateur d’Algosup veut s’appuyer sur les neurosciences pour « révolutionner les méthodes classiques d’apprentissage ». Dès l’an prochain, plus de notion de calendrier scolaire. « La formation fonctionnera 12 mois sur 12. Aucune vacance imposée. Efforts et rythmes seront librement modulés par les étudiants », résume Franck Jeannin. Du coup, le financement des études sera mensualisé.
