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 based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"present data algorithms" » "present art algorithms" (Expand Search), "present all algorithms" (Expand Search), "present both algorithms" (Expand Search), "presence data algorithms" (Expand Search), "present day algorithms" (Expand Search), "recent data algorithms" (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 based algorithms") OR ("present data algorithms"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element based algorithms\") OR (\"present data algorithms\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( element based algorithms ) OR ( present data algorithms ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element based algorithms") OR ("present data algorithms"))) OR ("data modeling algorithm"))*.
