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)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement atlas 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: (("elements method algorithm") OR ((("spatial mapping algorithm") OR ("movement data algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"spatial mapping algorithm\") OR (\"movement data algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( spatial mapping algorithm ) OR ( movement data algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("spatial mapping algorithm") OR ("movement data algorithm"))))*.
