search(data, **kwargs)

Perform a search for the nearest fuzzy sets of the point ‘data’. This function were designed to work with several overlapped fuzzy sets.

Parameters:

• data – the value to search for the nearest fuzzy sets
• type – the return type: ‘index’ for the fuzzy set indexes or ‘name’ for fuzzy set names.
• results – the number of nearest fuzzy sets to return

Returns:

a list with the nearest fuzzy sets
