Perhaps you should try some spelling variations:
parameter optimized » parameter optimization
optimized algorithm » optimized algorithms, optimizer algorithms
study algorithm » source algorithm
control study » controlled study
code control » mode control, case control, order control

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( code control study algorithm ) or ( modified parameter optimized algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code control study algorithm ) OR ( modified parameter optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( code control study algorithm ) or ( modified parameter optimized algorithm ))*.
