Perhaps you should try some spelling variations:
"data processin_ algorithm" » "data processing algorithm" (Expand Search), "data present algorithm" (Expand Search), "data promising algorithms" (Expand Search), "data preprocessing algorithm" (Expand Search), "waste processing algorithm" (Expand Search)
"element ore algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element erf algorithm" (Expand Search), "element te algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element model algorithm" (Expand Search)
"element g algorithm" » "element _ algorithm" (Expand Search), "element b algorithm" (Expand Search), "element gnb algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "element te 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 ore algorithm") OR ("element g algorithm"))) OR ("data processin_ algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element ore algorithm\") OR (\"element g algorithm\"))) OR (\"data processin_ algorithm\"))".
• Removing quotes may allow a broader search: (((( element ore algorithm ) OR ( element g algorithm ))) OR ( data processin_ algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element ore algorithm") OR ("element g algorithm"))) OR ("data processin_ algorithm"))*.
