Perhaps you should try some spelling variations:
"forest modeling algorithm" » "forest making algorithm" (Expand Search), "forest model algorithm" (Expand Search), "forest models algorithm" (Expand Search)
"fragment based algorithm" » "agent based algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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: (((("fragment based algorithm") OR ("relevant data algorithm"))) OR ("forest modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"fragment based algorithm\") OR (\"relevant data algorithm\"))) OR (\"forest modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( fragment based algorithm ) OR ( relevant data algorithm ))) OR ( forest modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("fragment based algorithm") OR ("relevant data algorithm"))) OR ("forest modeling algorithm"))*.
