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