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