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)
"present both algorithms" » "present art algorithms" (Expand Search), "present four algorithms" (Expand Search), "present box algorithm" (Expand Search), "present work algorithms" (Expand Search), "present high algorithms" (Expand Search), "present data algorithms" (Expand Search)
"elements two algorithms" » "elements ml algorithms" (Expand Search), "elements _ algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements wt algorithms" (Expand Search), "elements upon 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: (((("present both algorithms") OR ("elements two algorithms"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present both algorithms\") OR (\"elements two algorithms\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( present both algorithms ) OR ( elements two algorithms ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present both algorithms") OR ("elements two algorithms"))) OR ("data modeling algorithm"))*.
