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)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"fragment based algorithm" » "agent based 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: (("forest modeling algorithm") OR ((("fragment based algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"forest modeling algorithm\") OR (((\"fragment based algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( forest modeling algorithm ) OR ((( fragment based algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("forest modeling algorithm") OR ((("fragment based algorithm") OR ("element method algorithm"))))*.
