<div>Tournament graphs are used in discrete mathematics to represent a winning vertex in a graph.&nbsp;A tournament is a complete graph in which every pair of vertices are connected by a directed edge. These types of graphs are referred to as tournaments because each of the&nbsp;<span class="ltx_Math" contenteditable="false" data-equation="n">\(n\)</span>&nbsp;players competes against the other <span class="ltx_Math" contenteditable="false" data-equation="n-1">\(n-1\)</span>&nbsp;players  where ties are not allowed and the winner can be represented on a graph. These graphs are created by assigning every player a vertex and if player&nbsp;<span class="ltx_Math" contenteditable="false" data-equation="1">\(1\)</span>&nbsp;beats player&nbsp;<span class="ltx_Math" contenteditable="false" data-equation="2">\(2\)</span>, then a directed edge can be drawn with the arrow pointing from&nbsp;<span class="ltx_Math" contenteditable="false" data-equation="1">\(1\)</span>&nbsp;to&nbsp;<span class="ltx_Math" contenteditable="false" data-equation="2.">\(2.\)</span>&nbsp;Tournaments graphs  create Hamiltonian paths that go through each vertex. The Hamiltonian path theorem states that for every tournament there is a Hamiltonian path for&nbsp;<span class="ltx_Math" contenteditable="false" data-equation="n\ge1,">\(n\ge1,\)</span>&nbsp;for any tournament consisting of&nbsp;<span class="ltx_Math" contenteditable="false" data-equation="n">\(n\)</span>&nbsp;vertices in which there is always a sequence of vertices&nbsp;<span class="ltx_Math" contenteditable="false" data-equation="v_1,v_2,...,v_n">\(v_1,v_2,...,v_n\)</span>&nbsp;such that&nbsp;<span class="ltx_Math" contenteditable="false" data-equation="v_1\rightarrow v_2\rightarrow...\rightarrow v_n.">\(v_1\rightarrow v_2\rightarrow...\rightarrow v_n.\)</span><br></div>
