Perhaps you should try some spelling variations:
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"data groups algorithm" » "data growth algorithm" (Expand Search), "data adonis algorithm" (Expand Search), "data g:scs algorithm" (Expand Search), "data group algorithm" (Expand Search), "data grouped algorithm" (Expand Search), "data subgroups algorithm" (Expand Search)
"solved using algorithm" » "solved using algorithms" (Expand Search), "solved routing algorithm" (Expand Search), "solved fusion 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 method algorithm") OR ((("data groups algorithm") OR ("solved using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data groups algorithm\") OR (\"solved using algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data groups algorithm ) OR ( solved using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data groups algorithm") OR ("solved using algorithm"))))*.
