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 learning algorithm" » "elements learning algorithms" (Expand Search), "students learning algorithm" (Expand Search), "elements during algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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: (((("data using algorithm") OR ("data modeling algorithm"))) OR ("elements learning algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"data modeling algorithm\"))) OR (\"elements learning algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( data modeling algorithm ))) OR ( elements learning algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("data modeling algorithm"))) OR ("elements learning algorithm"))*.
