Perhaps you should try some spelling variations:
"develop targeted algorithms" » "develop three algorithms" (Expand Search), "develop tree algorithms" (Expand Search), "develop tested algorithms" (Expand Search), "developing targeted algorithms" (Expand Search)
"element data algorithms" » "element art algorithms" (Expand Search), "element all algorithms" (Expand Search), "element both algorithms" (Expand Search), "settlement data algorithms" (Expand Search), "relevant data algorithms" (Expand Search), "movement data algorithms" (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: (((("develop targeted algorithms") OR ("element data algorithms"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"develop targeted algorithms\") OR (\"element data algorithms\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( develop targeted algorithms ) OR ( element data algorithms ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("develop targeted algorithms") OR ("element data algorithms"))) OR ("data using algorithm"))*.
