Perhaps you should try some spelling variations:
"element modeling algorithm" » "element scheduling algorithm" (Expand Search), "elements modeling algorithm" (Expand Search)
"fragment based algorithm" » "agent based algorithm" (Expand Search), "gradient based algorithm" (Expand Search)
"element both algorithms" » "elements both algorithms" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("fragment based algorithm") OR ("element both algorithms"))) OR ("element modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"fragment based algorithm\") OR (\"element both algorithms\"))) OR (\"element modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( fragment based algorithm ) OR ( element both algorithms ))) OR ( element modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("fragment based algorithm") OR ("element both algorithms"))) OR ("element modeling algorithm"))*.
