Perhaps you should try some spelling variations:
"implementing routine algorithm" » "implement routine algorithm" (Expand Search), "implementing future algorithm" (Expand Search), "implementing context algorithm" (Expand Search), "implementing routing algorithm" (Expand Search), "implementing cosine algorithm" (Expand Search), "implementing retinex algorithm" (Expand Search)
"level using algorithm" » "level using algorithms" (Expand Search), "level routing algorithm" (Expand Search), "level fusion algorithm" (Expand Search), "levels using algorithm" (Expand Search)
"element ree algorithm" » "element tree algorithms" (Expand Search), "element new algorithm" (Expand Search), "element rf algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements res 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: (((("implementing routine algorithm") OR ("element ree algorithm"))) OR ("level using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implementing routine algorithm\") OR (\"element ree algorithm\"))) OR (\"level using algorithm\"))".
• Removing quotes may allow a broader search: (((( implementing routine algorithm ) OR ( element ree algorithm ))) OR ( level using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("implementing routine algorithm") OR ("element ree algorithm"))) OR ("level using algorithm"))*.
