Perhaps you should try some spelling variations:
"develop three algorithms" » "develop forest algorithms" (Expand Search), "develop based algorithms" (Expand Search), "develop art algorithms" (Expand Search), "develop tree algorithms" (Expand Search), "develop large algorithms" (Expand Search), "develop targeted algorithms" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"settlement data algorithm" » "settlement data algorithms" (Expand Search), "settlement update algorithm" (Expand Search), "settlement atlas 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 three algorithms") OR ("settlement data algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"develop three algorithms\") OR (\"settlement data algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( develop three algorithms ) OR ( settlement data algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("develop three algorithms") OR ("settlement data algorithm"))) OR ("data using algorithm"))*.
