DESCRIPTION

Constructors:

FlFRuleBase();

FlFRuleBase(FlParam *param);

FlFRuleBase(FlStringR name);

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

void add_rule(FlFRule *rule);

void add_rule(FlFRule &rule);

Adds rule to base.

void add_in_var(FlFVar *rule);

void add_in_var(FlFVar &rule);

void add_out_var(FlFVar *rule);

void add_out_var(FlFVar &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(FlFVar *var, FlFSet *set , double match, FlFSetArray &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(FlFVar *var, FlFSetArray &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.

Fl_bool updateFuzzySets(const char* filename);

Replaces the existing fuzzy sets with the sets specified in the file. It returns TRUE if the sets were updated, FALSE if there was a format error.

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

Debugs the output on &strm for fuzzy rules.
