Esiste un semplice algoritmo di attraversamento di un labirinto che garantisce il ritrovamento dell'uscista (sempre che c'è ne sia una). Nel caso ceh l'uscita non ci fosse vi ritrovereste di nuovo al punto di partenza. Poggiate la mano a destra sulla parete alla vostra destra e cominciate a camminare in avanti. Non rimuovete mai la vostra mano dalla parete. Se il labirinto svolta a destra, seguite il muro a destra. Alla fine ar riverete sicuramente all'uscita del labirinto, se nel frattempo non avete rimosso la vostra mano dalla parete. E' proba bile che esista un percorso piu' breve di quello che avete intrapreso, ma in questo modo avrete la certezza di uscire dal labirinto. Scrivete la funzoine ricorsiva mazeTraverse per attraversare il labirinto. La funzione dovrà ricevere come argomenti una matrice di caratteri 12 per 12, per rappresentare il labirinto, e la posizione di partenza all'interno dello stesso. Man mano che mazeTraverse tenterà di individuare l'uscita dal labirinto, dovrà inserire il carattere x in ogni casella del percorso. La funione dovrà visualizzare il labirinto dopo ogni mossa così che l'utente possa seguire la risuluzione del labirinto. (Generazione casuale di labirinti) Scrivete una funzione mazeGenerator che riceva come argomento una matrice di caratteri 12 per 12 e produca un labirinto a caso. La funzione dovrà anche restituire i punti di ingresso e di uscita del labirinto. Provate la vostra funzione mazeTraverse dell'Esercizio 7.25 utilizzando vari labirinti generati a caso (Lavirinti di qualsisi dimensione) Generalizzate le funzioni mazeTraverse dell'Esercizio 7.25 e 7.26, in modo da elaborare labirinti di qualsiasi larghezza e altezza. */ #include <stdio.h> #include <stdlib.h> #include <time.h> //#define SIZE 12 int size;

Currently "gauss" for gaussian noise or "poisson" For poisson noise, a deviate is drawn based on the value sky+flux in each pixel.

/* See LICENSE for license details. */ /* Module: feed_list.h Description: Generic linked list to be used for all lists in feed project. Comments: The list is a circular doubly linked list. A fake element is used to point to first and last elements. The same structure is used for each element including the fake element. However, the fake element does not have the same derived type as the other elements. The caller is reponsible of casting the element to the derived type. Before casting, it is important to make sure that the element is not the fake element. If the list is not the first member of the derived type, then it may be useful to use the offsetof() macro to get a pointer to the start of the derived type. The circular feature ensures that each element is part of a list. Operations may be done on a single element or on groups of elements. The same method is used to insert elements or to remove elements. See the examples section for more details. Examples: - create an empty list feed_list_init(&o_list); - insert a first list before a second feed_list_join(&o_first, &o_second); - insert a first list after a second feed_list_join(&o_second, &o_first); - remove a single element from a list feed_list_join(&o_element, &o_element); - remove a group of elements from a list feed_list_join(&o_last, &o_first); Notes: To insert all elements of a list into another, you first need to detach the elements from the fake or else the final list may end up with two fake elements. p_first = o_fake.p_next; feed_list_join(&o_fake, &o_fake); feed_list_join(p_first, &o_other); */ /* Header file dependencies */ #if !defined(INC_FEED_OS_H) #error include feed_os.h first #endif /* #if !defined(INC_FEED_OS_H) */ /* Reverse include guard */ #if defined(INC_FEED_LIST_H) #error include feed_list.h once #endif /* #if defined(INC_FEED_LIST_H) */ #define INC_FEED_LIST_H /* Structure: feed_list Description: */ struct feed_list { struct feed_list * p_next; struct feed_list * p_prev; }; /* struct feed_list */ /* Public functions ... */ void feed_list_init( struct feed_list * const p_node); void feed_list_join( struct feed_list * const p_before, struct feed_list * const p_after); /* end-of-file: feed_list.h */
