Perhaps you should try some spelling variations:
"implement routine algorithm" » "implement cosine algorithm" (Expand Search)
"present all algorithms" » "present _ algorithms" (Expand Search), "present value algorithms" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mesh 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: (((("present all algorithms") OR ("element mesh algorithm"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present all algorithms\") OR (\"element mesh algorithm\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( present all algorithms ) OR ( element mesh algorithm ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present all algorithms") OR ("element mesh algorithm"))) OR ("implement routine algorithm"))*.
