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)
"movement data algorithms" » "movement art algorithms" (Expand Search), "movement all algorithms" (Expand Search), "movement 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: (("image processing algorithm") OR ((("movement data algorithms") OR ("element ddpg algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"movement data algorithms\") OR (\"element ddpg algorithm\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( movement data algorithms ) OR ( element ddpg algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("movement data algorithms") OR ("element ddpg algorithm"))))*.
