Perhaps you should try some spelling variations:
"image 3_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_using algorithm" (Expand Search), "image 4_using algorithm" (Expand Search)
"settlement data algorithm" » "settlement data algorithms" (Expand Search), "settlement update algorithm" (Expand Search), "settlement atlas algorithm" (Expand Search)
"element based algorithm" » "engagement based 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 based algorithm"))) OR ("image 3_using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"settlement data algorithm\") OR (\"element based algorithm\"))) OR (\"image 3_using algorithm\"))".
• Removing quotes may allow a broader search: (((( settlement data algorithm ) OR ( element based algorithm ))) OR ( image 3_using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("settlement data algorithm") OR ("element based algorithm"))) OR ("image 3_using algorithm"))*.
