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