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)
"element both algorithms" » "element art algorithms" (Expand Search), "element four algorithms" (Expand Search), "element box algorithm" (Expand Search), "element data algorithms" (Expand Search), "element te algorithms" (Expand Search), "element mesh 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: (("element method algorithm") OR ((("spatial mapping algorithm") OR ("element both algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"spatial mapping algorithm\") OR (\"element both algorithms\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( spatial mapping algorithm ) OR ( element both algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("spatial mapping algorithm") OR ("element both algorithms"))))*.
