Perhaps you should try some spelling variations:
"image 1_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 1_single algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"settlement data algorithm" » "settlement data algorithms" (Expand Search), "settlement update algorithm" (Expand Search), "settlement 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: (((("settlement data algorithm") OR ("element method algorithm"))) OR ("image 1_using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"settlement data algorithm\") OR (\"element method algorithm\"))) OR (\"image 1_using algorithm\"))".
• Removing quotes may allow a broader search: (((( settlement data algorithm ) OR ( element method algorithm ))) OR ( image 1_using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("settlement data algorithm") OR ("element method algorithm"))) OR ("image 1_using algorithm"))*.
