Perhaps you should try some spelling variations:
"based modeling algorithm" » "based making algorithm" (Expand Search), "based model algorithm" (Expand Search), "based models algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element three algorithms" » "element forest algorithms" (Expand Search), "element based algorithms" (Expand Search), "element art algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (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: (("based modeling algorithm") OR ((("element method algorithm") OR ("element three algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based modeling algorithm\") OR (((\"element method algorithm\") OR (\"element three algorithms\"))))".
• Removing quotes may allow a broader search: (( based modeling algorithm ) OR ((( element method algorithm ) OR ( element three algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("based modeling algorithm") OR ((("element method algorithm") OR ("element three algorithms"))))*.
