Perhaps you should try some spelling variations:
"implement routine algorithm" » "implement routing algorithm" (Expand Search), "implement cosine algorithm" (Expand Search), "implement retinex algorithm" (Expand Search)
"settlement data algorithm" » "settlement data algorithms" (Expand Search), "settlement update algorithm" (Expand Search), "settlement atlas algorithm" (Expand Search)
"element box algorithm" » "element best algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "elements box 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 box algorithm") OR ("settlement data algorithm"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element box algorithm\") OR (\"settlement data algorithm\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( element box algorithm ) OR ( settlement data algorithm ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element box algorithm") OR ("settlement data algorithm"))) OR ("implement routine algorithm"))*.
