Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"powder using pre algorithm" » "powder using mppt algorithm", "powder using qspr algorithm", "powder using _ algorithm", "code using pre algorithm", "boiler using pre algorithm", "model using pre algorithm", "powder nursing pre algorithm", "powder using one algorithm", "powder using ph algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("powder using pre algorithm") or ("modified notion approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("powder using pre algorithm") OR ("modified notion approximation algorithms")).
• Removing quotes may allow a broader search: (( powder using pre algorithm ) or ( modified notion approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("powder using pre algorithm") or ("modified notion approximation algorithms"))*.
