Perhaps you should try some spelling variations:
"element mining algorithm" » "element finding algorithm" (Expand Search), "element making algorithm" (Expand Search), "element training algorithms" (Expand Search), "element mapping algorithm" (Expand Search), "element bonding algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element box algorithm" » "element best algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii 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 mining algorithm") OR ((("element method algorithm") OR ("element box algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element mining algorithm\") OR (((\"element method algorithm\") OR (\"element box algorithm\"))))".
• Removing quotes may allow a broader search: (( element mining algorithm ) OR ((( element method algorithm ) OR ( element box algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element mining algorithm") OR ((("element method algorithm") OR ("element box algorithm"))))*.
