DESCRIPTION

Constructors:

CNFRuleBase();

CNFRuleBase(CNParam *param);

CNFRuleBase(CNStringR name);

Initializes the CNFRuleBase with name as the object's name.

In addition to the member functions required by CNCL, CNFRuleBase provides:

void add_rule(CNFRule *rule);

void add_rule(CNFRule &rule);

Adds rule to base.

void add_in_var(CNFVar *rule);

void add_in_var(CNFVar &rule);

void add_out_var(CNFVar *rule);

void add_out_var(CNFVar &rule);

Adds input/output variables to the base.

int get_n_rules()const;

int get_n_in_vars()const;

int get_n_out_vars()const;

Returns the number of rules/input variables/output variables in this base.

int resolution()const;

Returns the output fuzzy set resolution.

void inference(CNFVar *var, CNFSet *set , double match, CNFSetArray &res);

Computes the inference set for variable var and value set, using value match of LHS aggregation. The result is stored in the array fuzzy set res.

void evaluate(CNFVar *var, CNFSetArray &res);

Computes output set for variable var, combining the inference() results of all rules. The result is stored in the array fuzzy set res.

void aggregate_all();

Aggregates all rules.

void evaluate_all();

Evaluates all variables.

void defuzzy_all();

Defuzzifies all output variables.

void debug_rules(ostream &strm=cout, int lvl=0);

Debugs the output on &strm for fuzzy rules.
