Perhaps you should try some spelling variations:
"image modeling algorithm" » "image scheduling algorithm" (Expand Search)
"agent learning algorithm" » "agent learning algorithms" (Expand Search), "student learning algorithm" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mesh 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: (("image modeling algorithm") OR ((("element mesh algorithm") OR ("agent learning algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image modeling algorithm\") OR (((\"element mesh algorithm\") OR (\"agent learning algorithm\"))))".
• Removing quotes may allow a broader search: (( image modeling algorithm ) OR ((( element mesh algorithm ) OR ( agent learning algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image modeling algorithm") OR ((("element mesh algorithm") OR ("agent learning algorithm"))))*.
