std::vector<Rule> heuristic_2(DataSetFid &trainDataset, Parameters &p, const std::vector<std::vector<double>> &hyperlocus)

Generates a list of rules covering all training samples using a faster but less optimal heuristic.

Generates rules for each training sample and filters the list of generated rules to remove duplicates and keep the rules that fit and cover all training samples. This is a faster version of the first heuristic ‘heuristic_1’, the only difference is that it doesn’t check every generated rule before choosing the best one. After removing duplicates, it directly selects a rule if one or more not already covered samples are covered by the rule, until all samples are covered.

Parameters:

• trainDataset – Class containing all usable data to compute the algorithm.

• p – Class containing all user-defined parameters that influences the program execution.

• hyperlocus – 2D vector of doubles representing all the possible hyperplanes used to compute the Fidex algorithm.

Returns:

A vector containing the computed rules.
