<p>In <a href="Mathematics" title="Mathematics">mathematics</a>, <b>random graph</b> is the general term to refer to <a href="Probability_distribution" title="Probability distribution">probability distributions</a> over <a href="Graph_(discrete_mathematics)" title="Graph (discrete mathematics)">graphs</a>. Random graphs may be described simply by a probability distribution, or by a <a href="Random_process" class="mw-redirect" title="Random process">random process</a> which generates them.<sup id="cite_ref-Random_Graphs_1-0" class="reference"><a href="#cite_note-Random_Graphs-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-Introduction_to_Random_graphs_2-0" class="reference"><a href="#cite_note-Introduction_to_Random_graphs-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> The theory of random graphs lies at the intersection between <a href="Graph_theory" title="Graph theory">graph theory</a> and <a href="Probability_theory" title="Probability theory">probability theory</a>. From a mathematical perspective, random graphs are used to answer questions about the properties of <i>typical</i> graphs. Its practical applications are found in all areas in which <a href="Complex_network" title="Complex network">complex networks</a> need to be modeled&nbsp;– many random graph models are thus known, mirroring the diverse types of complex networks encountered in different areas. In a mathematical context, <i>random graph</i> refers almost exclusively to the <a href="Erd%C5%91s%E2%80%93R%C3%A9nyi_model" title="Erdős–Rényi model">Erdős–Rényi random graph model</a>. In other contexts, any graph model may be referred to as a <i>random graph</i>.

<p>A random graph is obtained by starting with a set of <i>n</i> isolated vertices and adding successive edges between them at random.

<p>It turns out that if the vertex set is <a href="Countable" class="mw-redirect" title="Countable">countable</a> then there is, <a href="Up_to" title="Up to">up to</a> <a href="Graph_isomorphism" title="Graph isomorphism">isomorphism</a>, only a single graph with this property, namely the <a href="Rado_graph" title="Rado graph">Rado graph</a>. Thus any countably infinite random graph is almost surely the Rado graph, which for this reason is sometimes called simply the <b>random graph</b>. However, the analogous result is not true for uncountable graphs, of which there are many (nonisomorphic) graphs satisfying the above property.
