Perhaps you should try some spelling variations:
"end modeling algorithm" » "end making algorithm" (Expand Search), "3d modeling algorithm" (Expand Search), "ann modeling algorithm" (Expand Search), "cfd modeling algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"cell clustering algorithm" » "cell clusters algorithm" (Expand Search), "means 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: (((("cell clustering algorithm") OR ("end modeling algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"cell clustering algorithm\") OR (\"end modeling algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( cell clustering algorithm ) OR ( end modeling algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("cell clustering algorithm") OR ("end modeling algorithm"))) OR ("element method algorithm"))*.
