Perhaps you should try some spelling variations:
"element contents algorithm" » "element consensus algorithm" (Expand Search), "element consistent algorithm" (Expand Search), "element control algorithm" (Expand Search), "element content algorithm" (Expand Search), "pigment contents algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement 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 contents algorithm") OR ("element data algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element contents algorithm\") OR (\"element data algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( element contents algorithm ) OR ( element data algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element contents algorithm") OR ("element data algorithm"))) OR ("data using algorithm"))*.
