Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"code control law algorithm" » "code control adam algorithm", "code control _ algorithm", "code control mom algorithm", "mode control law algorithm", "case control law algorithm", "order control law algorithm", "code control a algorithm", "code contract law algorithm", "code control case algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("code control law algorithm") OR ("modified notion approximation algorithms"))~.
• Removing quotes may allow a broader search: (( code control law algorithm ) or ( modified notion approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("code control law algorithm") or ("modified notion approximation algorithms"))*.
