Function Documentation

CA* createCA

(

int

size

)

Creates a new CA ready for use, all malloc'd and all.

Parameters:

size

The desired dimension of the new CA.

See also:

freeCA()

Returns:

The newly created CA.

Definition at line 245 of file makeCAvid.c.

void createVideo	(	int	width,
		int	height
	)

Definition at line 120 of file makeCAvid.c.

int finished

(

CA *

ca

)

Indicates whether or not a CA has been completedly classified, i.e.

whether or not the CA is either all ones or all zeros.

Parameters:

ca

The CA for which to determine whether or not it is fully classified.

Returns:

A zero or one indicating whether or not the specified CA is fully classified.

Definition at line 232 of file makeCAvid.c.

CA* getInitCA	(	char *	file,
		int	size
	)

Pulls a CA of specified size from a file given by the specified file name.

The CA should all be on one line and just be a string of ones and zeros with no separation.

Parameters:

	file	The name of the file that contains the CA configuration.
	size	The size of the CA in the file.

Returns:

A pointer to the CA that was pulled from the file.

Definition at line 192 of file makeCAvid.c.

int* getRule

(

char *

file

)

Pulls a rule for the CA from a specified file.

The rule should be contained entirely on one line.

Parameters:

file

The name of the file that contains the rule.

Returns:

A pointer to an array of integers, which is really the ruleset.

Definition at line 167 of file makeCAvid.c.

int main	(	int	argc,
		char **	argv
	)

Definition at line 42 of file makeCAvid.c.

void outputImages	(	CA *	ca,
		int	nimage
	)

Definition at line 142 of file makeCAvid.c.

void printCA

(

CA *

ca

)

Prints to stdout the CA in its normal form.

Parameters:

ca

The CA to print to the screen.

See also:

printInternalCA()

Definition at line 293 of file makeCAvid.c.

void printInternalCA

(

CA *

ca

)

Prints to stdout our internal representation of the specified CA.

Parameters:

ca

The CA whose internal representaiton will be printed.

See also:

printCA()

Definition at line 280 of file makeCAvid.c.

void simulate	(	CA *	ca,
		int *	rule
	)

Definition at line 95 of file makeCAvid.c.

int step	(	CA *	curr,
		CA *	next,
		int *	rules
	)

Performs the transition for one generation of the CA to the next, based on the specified rule set.

The current CA is passed and remains unmodified, with its next generation being put into the CA, next.

Parameters:

	curr	The current generation.
	next	The next generation.
	rules	The rule set that governs how a CA should be updated.
