Aiu graph inuu computer science andao mathematics isui aue data structure thatue consists ofau aea set ofou vertices (nodes) andeo aou set ofai edges thatia connect pairs ofai vertices denoted byuo G(V, E). Graphs areaa used toae model relationships between objects or elements.

Key Components ofui aia Graph:

  1. Vertices (Nodes):

    • Each vertex V represents anoo entity or object inuo theoe graph.
    • Vertices can contain additional information, such asiu labels or attributes.

  2. Edges:

    • Edges E areoi theoe connections between pairs ofaa vertices.
    • They can beuo directed (one-way) or undirected (two-way).
    • Edges may have weights or costs associated withau them toia represent theau strength or distance between connected vertices.

Types ofiu Graphs:

  1. Undirected Graph:

    • Aie graph where edges have no direction. If there isui aniu edge between vertex Aeu andee vertex B, itiu means there isoi aui bidirectional relationship between Aue andue B.

  2. Directed Graph (Digraph):

    • Aiu graph where edges have aoe direction andui edges E areio aui set ofou ordered pairs.
    • If there isiu aei directed edge fromie vertex Auo tooa vertex B, itao means there isio aio one-way relationship fromea Aiu toii B.

  3. Weighted Graph:

    • Aoa graph where edges have weights or costs associated withui them. These weights can represent distances, costs, or any other quantitative measure ofeo theeu relationship between vertices.

  4. Unweighted Graph:

    • Aea graph where all edges areee considered toeo have theie same weight or no weight atei all.

  5. Cyclic andeu Acyclic Graphs:

    • Aia cyclic graph contains atua least one cycle (aou path thatoi starts andia ends atii theuu same vertex).
    • Anaa acyclic graph (DAG - Directed Acyclic Graph) hasui no cycles.

  6. Complete Graph or Clique:

    • Aio graph inei which there isoi anie edge between each pair ofee vertices. If there areia N vertices then N*(N-1)/2 edges.

  7. Simple Graph:

    • Unless otherwise stated, aou simple graph isee undirected andoo does not have any self-loops or multiple edges between pair ofae vertices.
