Perhaps you should try some spelling variations:
identification algorithm » detection algorithm (Expand Search)
driven optimization » level optimization (Expand Search), spider optimization (Expand Search)
may service » au service (Expand Search), may serve (Expand Search)
binary may » binary rat (Expand Search)
mask » masks (Expand Search), mass (Expand Search), task (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( binary may service identification algorithm ) OR ( binary mask driven optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary may service identification algorithm ) OR ( binary mask driven optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary may service identification algorithm ) OR ( binary mask driven optimization algorithm ))*.
