Perhaps you should try some spelling variations:
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"spatial mapping algorithm" » "spatial modeling algorithm" (Expand Search)
"element update algorithm" » "elements update algorithm" (Expand Search), "element updated 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: (("spatial mapping algorithm") OR ((("element method algorithm") OR ("element update algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"spatial mapping algorithm\") OR (((\"element method algorithm\") OR (\"element update algorithm\"))))".
• Removing quotes may allow a broader search: (( spatial mapping algorithm ) OR ((( element method algorithm ) OR ( element update algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("spatial mapping algorithm") OR ((("element method algorithm") OR ("element update algorithm"))))*.
