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