Perhaps you should try some spelling variations:
"spatial mapping algorithm" » "spatial making algorithm" (Expand Search), "spatial mining algorithm" (Expand Search), "spatial learning algorithm" (Expand Search), "spatial modeling algorithm" (Expand Search), "spatial planning algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (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: (((("relevant data algorithms") OR ("element method algorithm"))) OR ("spatial mapping algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithms\") OR (\"element method algorithm\"))) OR (\"spatial mapping algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithms ) OR ( element method algorithm ))) OR ( spatial mapping algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithms") OR ("element method algorithm"))) OR ("spatial mapping algorithm"))*.
