Perhaps you should try some spelling variations:
"data modelling algorithm" » "data modeling algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element finding algorithm" » "element bonding algorithm" (Expand Search), "recent finding algorithm" (Expand Search), "present findings 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: (((("element finding algorithm") OR ("element method algorithm"))) OR ("data modelling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element finding algorithm\") OR (\"element method algorithm\"))) OR (\"data modelling algorithm\"))".
• Removing quotes may allow a broader search: (((( element finding algorithm ) OR ( element method algorithm ))) OR ( data modelling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element finding algorithm") OR ("element method algorithm"))) OR ("data modelling algorithm"))*.
