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)
"image clustering algorithm" » "flare clustering algorithm" (Expand Search), "kmeans clustering algorithm" (Expand Search), "means clustering algorithm" (Expand Search)
"element update algorithm" » "element pass algorithm" (Expand Search), "element data algorithms" (Expand Search), "element ipca algorithm" (Expand Search), "element data 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: (((("image clustering algorithm") OR ("data modeling algorithm"))) OR ("element update algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image clustering algorithm\") OR (\"data modeling algorithm\"))) OR (\"element update algorithm\"))".
• Removing quotes may allow a broader search: (((( image clustering algorithm ) OR ( data modeling algorithm ))) OR ( element update algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("image clustering algorithm") OR ("data modeling algorithm"))) OR ("element update algorithm"))*.
