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