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)
"elements based algorithms" » "elements based algorithm" (Expand Search), "experiments based algorithms" (Expand Search), "elements related algorithms" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh 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: (((("elements based algorithms") OR ("element means algorithm"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements based algorithms\") OR (\"element means algorithm\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements based algorithms ) OR ( element means algorithm ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements based algorithms") OR ("element means algorithm"))) OR ("data modeling algorithm"))*.
