Perhaps you should try some spelling variations:
"element modeling algorithm" » "element scheduling algorithm" (Expand Search), "elements modeling algorithm" (Expand Search)
"client sampling algorithm" » "client scheduling algorithm" (Expand Search)
"element abs algorithm" » "element jaya algorithm" (Expand Search), "element rd algorithm" (Expand Search), "elements abs 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: (("element abs algorithm") OR ((("element modeling algorithm") OR ("client sampling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element abs algorithm\") OR (((\"element modeling algorithm\") OR (\"client sampling algorithm\"))))".
• Removing quotes may allow a broader search: (( element abs algorithm ) OR ((( element modeling algorithm ) OR ( client sampling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element abs algorithm") OR ((("element modeling algorithm") OR ("client sampling algorithm"))))*.
