Es una técnica de programación para hacer
búsqueda sistemática a través de todas las
configuraciones posibles dentro de un espacio
de búsqueda.
 Representación de la solución en una tupla
(X1; : : : ; Xn)
 Una función objetivo para determinar si la
tupla a analizar es una solución
 Unas restricciones a los candidatos para
rellenar la tupla:
Implícitas del problema. Valores que puede tomar
cada valor Xi
Explícitas o externas al problema. Por ejemplo,
problema mochila, el peso no debe superar la
capacidad de la mochila
 Una función de poda para eliminar partes del
árbol de búsqueda.
 Organización del problema en un árbol de
búsqueda.
 Construir la solución al problema en distintas
etapas.
 En cada paso se elige un candidato y se
añade a la solución, y se avanza en la
solución parcial.
 Si no es posible continuar en la construcción
hacia una solución completa, se abandona
ésta y la última componente se cambia por
otro valor.
 Si no quedan más valores por probar, se
retrocede al candidato anterior, se desecha, y
se selecciona otro candidato.
En las siguientes diapositivas les mostraremos
como el tiene todas las posibles soluciones que
puede tener el algoritmo y revisara todas las
soluciones e irán viendo paso por paso como
avanza esta técnica y como es su movimiento
en el algoritmo
