            \istroot(6)(2-2)[min]
            \istb{}{-1}[[circle, draw, yshift = 2pt, minimum size = 0.75cm] below] \istb{}{0}[[circle, draw, yshift = 2pt, minimum size = 0.75cm] below] \endist

Producción:

minimum sizees parte de la solución, pero ¿hay alguna forma de alinear los valores terminales con los que están dentro del círculo más grande? (Tenga en cuenta que los valores terminales se enumeran incorrectamente para obtener este resultado)

Answer 1

Una forma de hacerlo es utilizar \xtShowEndPointsseguido de xtShowTerminalNodes:

\documentclass[12pt,border=2pt]{standalone}
\usepackage{istgame}
%\usepackage{tikz}
%\usetikzlibrary{shapes,arrows.meta, positioning}

\begin{document}    

\begin{istgame}
\setistNewNodeStyle{max}
  [regular polygon, regular polygon sides = 3]{1.5cm}
\setistNewNodeStyle{min}
  [regular polygon, regular polygon sides = 3, shape border rotate = 180]{1.5cm}
\setistNewNodeStyle{chance}
  [circle]{1.2cm}
\def\distFactor{20};
\xtdistance{\distFactor mm}{4*\distFactor mm}
\setxtarrowtips[blue, thick]
\istroot(0)[max]<center, blue>{1.5}
  \istb[blue, ->-] 
  \istb 
  \endist
\xtdistance{\distFactor mm}{2*\distFactor mm}
\istroot(1)(0-1)[chance]<center, purple>{1.5}
  \istb{0.5}[al] 
  \istb{0.5}[ar] 
  \endist
\istroot(2)(0-2)[chance]<center, purple>{$\leq 1$}
  \istb{0.5}[al] 
  \istb{0.5}[ar] 
  \endist
%% terminal nodes with or without circles (TRICK!!)
\xtShowEndPoints[circle,draw,minimum size=1.1cm] % comes before \xtShowTerminalNodes
\xtShowTerminalNodes[circle,draw=none,minimum size=1.1cm]
\xtdistance{\distFactor mm}{\distFactor mm}
\istroot(3)(1-1)[min]<center, red>{2}
  \istbt{}{2}[center]   %
  \istb{}{5000}[center] 
  \endist
\istroot(4)(1-2)[min]<center, red>{1}
  \istbt{}{1}[center]   %
  \istb{}{100}[center] 
  \endist
\istroot(5)(2-1)[min]<center, red>{0}
  \istbt{}{0}[center]   %
  \istb{}{2}[center] 
  \endist
\istroot(6)(2-2)[min]
  \istb{}{-1}[center] 
  \istb{}{0}[center] 
  \endist
\end{istgame}

\end{document}
