Perhaps you should try some spelling variations:
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"element atlas algorithm" » "element anbs algorithm" (Expand Search), "element abs algorithm" (Expand Search), "element adonis algorithm" (Expand Search), "element data algorithm" (Expand Search)
"gmm clustering algorithm" » "_ clustering algorithm" (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 modeling algorithm") OR ("gmm clustering algorithm"))) OR ("element atlas algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data modeling algorithm\") OR (\"gmm clustering algorithm\"))) OR (\"element atlas algorithm\"))".
• Removing quotes may allow a broader search: (((( data modeling algorithm ) OR ( gmm clustering algorithm ))) OR ( element atlas algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data modeling algorithm") OR ("gmm clustering algorithm"))) OR ("element atlas algorithm"))*.
