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