In computer science, lexicographic breadth-first search or Lex-BFS is a linear time algorithm for ordering the vertices of a graph. The algorithm is different from a breadth-first search , but it produces an ordering that is consistent with breadth-first search.
Breadth-first search (BFS) is an algorithm for searching a tree data structure for a node that satisfies a given property. It starts at the tree root and explores all nodes at the present depth prior to moving on to the nodes at the next depth level.
Bootstrap:Algebra can be integrated into a standalone CS or mainstream math class, and aligns with national and state math standards. And since every child takes algebra - regardless of gender or background - Bootstrap is one of the largest providers of formal CS education to girls and underrepresented students nationwide.
The ACM Computing Classification System (CCS) is a similar hierarchical classification scheme for computer science. There is some overlap between the AMS and ACM classification schemes, in subjects related to both mathematics and computer science, however the two schemes differ in the details of their organization of those topics.
In computer science, a graph is an abstract data type that is meant to implement the undirected graph and directed graph concepts from the field of graph theory within mathematics. A graph data structure consists of a finite (and possibly mutable) set of vertices (also called nodes or points ), together with a set of unordered pairs of these ...
The girth of an undirected graph can be computed by running a breadth-first search from each node, with complexity () where is the number of vertices of the graph and is the number of edges. [7] A practical optimization is to limit the depth of the BFS to a depth that depends on the length of the smallest cycle discovered so far. [ 8 ]
In computer science, graph traversal (also known as graph search) refers to the process of visiting (checking and/or updating) each vertex in a graph. Such traversals are classified by the order in which the vertices are visited. Tree traversal is a special case of graph traversal.
The breadth-first approach of visiting each child on the same level of the tree is an instance of dovetailing, where a single step is performed for every program before moving to the next. Thus, progress is made in each program, regardless of the potential existence of a non-terminating program.
