Perhaps you should try some spelling variations:
"element matching algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "employment matching algorithm" (Expand Search)
"student learning algorithm" » "student learning algorithms" (Expand Search)
"elements wt algorithm" » "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements rf algorithm" (Expand Search), "elements b algorithm" (Expand Search), "elements fe 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 wt algorithm") OR ((("element matching algorithm") OR ("student learning algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements wt algorithm\") OR (((\"element matching algorithm\") OR (\"student learning algorithm\"))))".
• Removing quotes may allow a broader search: (( elements wt algorithm ) OR ((( element matching algorithm ) OR ( student learning algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements wt algorithm") OR ((("element matching algorithm") OR ("student learning algorithm"))))*.
