Perhaps you should try some spelling variations:
"develop tested algorithms" » "develop based algorithms" (Expand Search), "develop best algorithms" (Expand Search), "develop based algorithm" (Expand Search), "levels tested 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)
"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)

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 ((("develop tested algorithms") OR ("element data algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data using algorithm\") OR (((\"develop tested algorithms\") OR (\"element data algorithms\"))))".
• Removing quotes may allow a broader search: (( data using algorithm ) OR ((( develop tested algorithms ) OR ( element data algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data using algorithm") OR ((("develop tested algorithms") OR ("element data algorithms"))))*.
