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 five algorithms" » "element four algorithms" (Expand Search), "element forest algorithms" (Expand Search), "element based algorithms" (Expand Search), "element fbe algorithms" (Expand Search), "element citre algorithms" (Expand Search), "element te algorithms" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant 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: (("relevant data algorithm") OR ((("implement routing algorithm") OR ("element five algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithm\") OR (((\"implement routing algorithm\") OR (\"element five algorithms\"))))".
• Removing quotes may allow a broader search: (( relevant data algorithm ) OR ((( implement routing algorithm ) OR ( element five algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithm") OR ((("implement routing algorithm") OR ("element five algorithms"))))*.
