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 mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"element ii algorithm" » "element _ algorithm" (Expand Search), "element _ algorithms" (Expand Search), "element g algorithm" (Expand Search), "element te 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 ii algorithm") OR ((("implement routine algorithm") OR ("element mapping algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element ii algorithm\") OR (((\"implement routine algorithm\") OR (\"element mapping algorithm\"))))".
• Removing quotes may allow a broader search: (( element ii algorithm ) OR ((( implement routine algorithm ) OR ( element mapping algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element ii algorithm") OR ((("implement routine algorithm") OR ("element mapping algorithm"))))*.
