Perhaps you should try some spelling variations:
"alignment based algorithm" » "alignment used algorithm" (Expand Search), "alignments used algorithm" (Expand Search), "management based 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)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element data algorithm") OR ("alignment based algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element data algorithm\") OR (\"alignment based algorithm\"))) OR (\"data using algorithm\"))*".
• Removing quotes may allow a broader search: (((( element data algorithm ) OR ( alignment based algorithm ))) OR ( data using algorithm ))*.
