Perhaps you should try some spelling variations:
"element modeling algorithm" » "element scheduling algorithm" (Expand Search), "elements modeling algorithm" (Expand Search)
"data using algorithm" » "data cosine algorithm" (Expand Search)
"element mdem algorithms" » "elements mdem algorithms" (Expand Search), "element dem algorithms" (Expand Search), "element adem algorithms" (Expand Search), "element mdea 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 ((("element mdem algorithms") OR ("element modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data using algorithm\") OR (((\"element mdem algorithms\") OR (\"element modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( data using algorithm ) OR ((( element mdem algorithms ) OR ( element modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data using algorithm") OR ((("element mdem algorithms") OR ("element modeling algorithm"))))*.
