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 pass algorithm" » "element lasso algorithm" (Expand Search), "element pso algorithm" (Expand Search), "element rast algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"neural finding algorithm" » "neural fitting algorithm" (Expand Search), "neural coding 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 pass algorithm") OR ((("implement routine algorithm") OR ("neural finding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element pass algorithm\") OR (((\"implement routine algorithm\") OR (\"neural finding algorithm\"))))".
• Removing quotes may allow a broader search: (( element pass algorithm ) OR ((( implement routine algorithm ) OR ( neural finding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element pass algorithm") OR ((("implement routine algorithm") OR ("neural finding algorithm"))))*.
