Perhaps you should try some spelling variations:
"image 3_routing algorithm" » "image routing algorithm" (Expand Search), "image boosting algorithm" (Expand Search), "image 3_resting algorithm" (Expand Search), "image 3_using algorithm" (Expand Search), "image 3_targeting algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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 ((("data using algorithm") OR ("image 3_routing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"settlement data algorithm\") OR (((\"data using algorithm\") OR (\"image 3_routing algorithm\"))))".
• Removing quotes may allow a broader search: (( settlement data algorithm ) OR ((( data using algorithm ) OR ( image 3_routing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("settlement data algorithm") OR ((("data using algorithm") OR ("image 3_routing algorithm"))))*.
