    Definición: Trayectoria trivial

    un camino que consiste en un solo vértice

    Definición: Ciclo

    un camino cerrado

    Definición: Ciclo adecuado

    un ciclo no trivial que también es un sendero

    Nota\(\PageIndex{1}\)

    Si\(G\) contiene vértices\(v,v'\) y borde\(e = \{v,v'\}\text{,}\) entonces\(v,e,v',e,v\) es un ciclo no trivial que no es apropiado.

    Definición: Gráfica acíclica

    no contiene ciclos adecuados

    Definición: Bosque

    sinónimo de gráfico acíclico

    Definición: Árbol

    una gráfica acíclica conectada

    Ejemplo\(\PageIndex{1}\): A forest of trees.

    La gráfica en la Figura\(\PageIndex{1}\) es acíclica. Cada uno de sus componentes conectados es un árbol.

    Figura\(\PageIndex{1}\): Gráfica acíclica no conectada.

    Ejemplo\(\PageIndex{2}\): Decision trees are trees.

    En el Ejemplo Trabajado 15.2.3, intentamos determinar todos los senderos posibles de un nodo a otro en una gráfica dada. La gráfica de la Figura 15.2.2 que usamos para explorar posibles senderos en la gráfica dada es un ejemplo de un árbol de decisión — en cada nodo nos “ramificamos” a nuevas posibilidades para continuar el sendero. Como sugiere el nombre, la gráfica conectada con la que terminamos es un árbol.
