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), "implemented routine algorithm" (Expand Search), "implementing routine algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"elements mean algorithm" » "elements means algorithm" (Expand Search), "elements new algorithm" (Expand Search), "elements each algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element mesh 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: (((("implement routine algorithm") OR ("elements mean algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implement routine algorithm\") OR (\"elements mean algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( implement routine algorithm ) OR ( elements mean algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("implement routine algorithm") OR ("elements mean algorithm"))) OR ("level coding algorithm"))*.
