Perhaps you should try some spelling variations:
"defect generation algorithm" » "defect genetic algorithm" (Expand Search), "defect detection algorithm" (Expand Search), "next generation algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"data using algorithm" » "data cosine 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: (("data using algorithm") OR ((("element method algorithm") OR ("defect generation algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data using algorithm\") OR (((\"element method algorithm\") OR (\"defect generation algorithm\"))))".
• Removing quotes may allow a broader search: (( data using algorithm ) OR ((( element method algorithm ) OR ( defect generation algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data using algorithm") OR ((("element method algorithm") OR ("defect generation algorithm"))))*.
