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)
"elements cc3d algorithm" » "elements cscap algorithm" (Expand Search), "elements cnn algorithm" (Expand Search), "elements wold algorithm" (Expand Search), "elements crcy algorithm" (Expand Search), "elements ices algorithm" (Expand Search), "elements uce 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)

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: (((("elements cc3d algorithm") OR ("element two algorithms"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements cc3d algorithm\") OR (\"element two algorithms\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( elements cc3d algorithm ) OR ( element two algorithms ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements cc3d algorithm") OR ("element two algorithms"))) OR ("implement routine algorithm"))*.
