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