Perhaps you should try some spelling variations:
"data model algorithm" » "data novel algorithm" (Expand Search), "data modbo algorithm" (Expand Search), "data modeling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"develop two algorithms" » "develop ml algorithms" (Expand Search), "develop _ algorithms" (Expand Search), "develop art algorithms" (Expand Search), "developed two algorithms" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: (((("develop two algorithms") OR ("element data algorithm"))) OR ("data model algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"develop two algorithms\") OR (\"element data algorithm\"))) OR (\"data model algorithm\"))".
• Removing quotes may allow a broader search: (((( develop two algorithms ) OR ( element data algorithm ))) OR ( data model algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("develop two algorithms") OR ("element data algorithm"))) OR ("data model algorithm"))*.
