Perhaps you should try some spelling variations:
"yield routing algorithm" » "yield modeling algorithm" (Expand Search), "yield finding algorithm" (Expand Search), "yield making algorithm" (Expand Search), "yield using algorithm" (Expand Search)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"data clustering algorithm" » "deep clustering algorithm" (Expand Search), "spatial clustering algorithm" (Expand Search), "dbscan clustering 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: (("elements method algorithm") OR ((("data clustering algorithm") OR ("yield routing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data clustering algorithm\") OR (\"yield routing algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data clustering algorithm ) OR ( yield routing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data clustering algorithm") OR ("yield routing algorithm"))))*.
