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)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te algorithm" (Expand Search)
"present all algorithms" » "present ml algorithms" (Expand Search), "present art algorithms" (Expand Search), "present rl algorithms" (Expand Search), "present salt algorithms" (Expand Search), "present a algorithms" (Expand Search), "present value 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: (((("element mesh algorithm") OR ("present all algorithms"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mesh algorithm\") OR (\"present all algorithms\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( element mesh algorithm ) OR ( present all algorithms ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mesh algorithm") OR ("present all algorithms"))) OR ("implement routine algorithm"))*.
