Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"element ddpg algorithm" » "element ppo algorithm" (Expand Search), "element dbo algorithm" (Expand Search), "element hip algorithm" (Expand Search), "element g algorithm" (Expand Search), "element data 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 ddpg algorithm") OR ("relevant data algorithms"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element ddpg algorithm\") OR (\"relevant data algorithms\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element ddpg algorithm ) OR ( relevant data algorithms ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element ddpg algorithm") OR ("relevant data algorithms"))) OR ("image processing algorithm"))*.
