Function Documentation

void freedom	(	int **	rules,
		int	popSize,
		double *	fits
	)

Free a lot of dynamically allocated memory used by this program.

Definition at line 170 of file caga.c.

int ** getRules	(	char *	file,
		int	popSize
	)

Gets the entire population of rules from the given file.

Parameters:

	file	The text file containing the entire population.
	popSize	The size of the population of rules, used for knowing when to stop extracting the memeber.

Returns:

The list of rules, and remember that the rules are a list of ints, so hence a matrix is returned.

Definition at line 190 of file caga.c.

int main	(	int	argc,
		char **	argv
	)

Definition at line 37 of file caga.c.

void outputFitnesses	(	double *	fits,
		int	popSize
	)

Outputs all of the fitnesses to the output file.

Parameters:

	fits	The list of fitnesses.
	The	size of the population, in order to know when to stop traversing the array of fitnesses.

Definition at line 150 of file caga.c.

double * simulate	(	int **	pop,
		int	popSize,
		int	caSize,
		int	nStates,
		int	nIters
	)

Goes through the entire population, calculating the fitness of each member.

Parameters:

	pop	The set of rules that make up the population.
	popSize	The number of members in the population.
	caSize	The dimension of the square CA.
	nStates	The number of states that should be evaluated in order to determine the fitness of each member.
	nIters	The number of iterations that each evaluated CA should go through. Also can be thought of as the maximum number of iterations that a rule has to successfully classify the CA.

Returns:

An array of the fitnesses for each member. Each value in the array is the corresponding fitness of the member at the same index in the population.

Definition at line 235 of file caga.c.

void usage

(

)

Indicates how to use the program properly.

Explains how to use this program.

Definition at line 286 of file caga.c.

int verboseMain

(

char **

argv

)

Identical to the main() function, except that verbosity is used.

Parameters:

argv

The parameters passed to the program.

Returns:

An integer indicating the state of the program.

Definition at line 96 of file caga.c.
