Perhaps you should try some spelling variations:
"implement retinex algorithm" » "implement cosine algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"present modbo algorithm" » "present mould 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: (("present modbo algorithm") OR ((("implement retinex algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present modbo algorithm\") OR (((\"implement retinex algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( present modbo algorithm ) OR ((( implement retinex algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("present modbo algorithm") OR ((("implement retinex algorithm") OR ("neural coding algorithm"))))*.
