Perhaps you should try some spelling variations:
"data making algorithm" » "data cosine algorithm" (Expand Search), "data mining algorithm" (Expand Search)
"based clustering algorithm" » "data clustering algorithm" (Expand Search)
"element tree algorithms" » "elements tree algorithms" (Expand Search), "element three algorithms" (Expand Search), "element free algorithms" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("data making algorithm") OR ("based clustering algorithm"))) OR ("element tree algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data making algorithm\") OR (\"based clustering algorithm\"))) OR (\"element tree algorithms\"))".
• Removing quotes may allow a broader search: (((( data making algorithm ) OR ( based clustering algorithm ))) OR ( element tree algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data making algorithm") OR ("based clustering algorithm"))) OR ("element tree algorithms"))*.
