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