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)
"defined making algorithm" » "defined learning algorithm" (Expand Search), "defined finding algorithm" (Expand Search), "defined means algorithm" (Expand Search), "defined using algorithm" (Expand Search), "defined ring algorithm" (Expand Search), "defined mucin algorithm" (Expand Search)
"data modeling algorithm" » "data modelling algorithm" (Expand Search), "data models 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 modeling algorithm") OR ("defined making algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data modeling algorithm\") OR (\"defined making algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data modeling algorithm ) OR ( defined making algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data modeling algorithm") OR ("defined making algorithm"))))*.
