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)
"imaging using algorithms" » "imaging pacing algorithms" (Expand Search), "imaging nine algorithms" (Expand Search), "imaging sorting algorithms" (Expand Search), "images using algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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: (((("imaging using algorithms") OR ("data modeling algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"imaging using algorithms\") OR (\"data modeling algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( imaging using algorithms ) OR ( data modeling algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("imaging using algorithms") OR ("data modeling algorithm"))) OR ("element method algorithm"))*.
