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 custom algorithm" » "elements fusion algorithm" (Expand Search), "elements control algorithm" (Expand Search), "elements lasso algorithm" (Expand Search)
"elements ii algorithm" » "elements _ algorithm" (Expand Search), "elements _ algorithms" (Expand Search), "elements b algorithm" (Expand Search), "elements fe 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: (((("elements custom algorithm") OR ("elements ii algorithm"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements custom algorithm\") OR (\"elements ii algorithm\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( elements custom algorithm ) OR ( elements ii algorithm ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements custom algorithm") OR ("elements ii algorithm"))) OR ("implement routine algorithm"))*.
