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