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 two algorithms" » "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element art algorithms" (Expand Search), "element te algorithms" (Expand Search)
"element box algorithm" » "element best algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii 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 two algorithms") OR ("element box algorithm"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element two algorithms\") OR (\"element box algorithm\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( element two algorithms ) OR ( element box algorithm ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element two algorithms") OR ("element box algorithm"))) OR ("implement routine algorithm"))*.
