Perhaps you should try some spelling variations:
"query modeling algorithm" » "query making algorithm" (Expand Search), "energy modeling algorithm" (Expand Search), "key modeling algorithm" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (Expand Search)
"elements based algorithm" » "experiments based algorithm" (Expand Search), "elements related 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: (((("elements based algorithm") OR ("element tree algorithms"))) OR ("query modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements based algorithm\") OR (\"element tree algorithms\"))) OR (\"query modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements based algorithm ) OR ( element tree algorithms ))) OR ( query modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements based algorithm") OR ("element tree algorithms"))) OR ("query modeling algorithm"))*.
