Perhaps you should try some spelling variations:
"data modeling algorithm" » "data scheduling algorithm" (Expand Search), "data models algorithm" (Expand Search), "spatial modeling algorithm" (Expand Search)
"based clustering algorithm" » "data clustering algorithm" (Expand Search)
"element both algorithms" » "elements both algorithms" (Expand Search)

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

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