Perhaps you should try some spelling variations:
"powder using method algorithm" » "powder using mom algorithm", "code using method algorithm", "boiler using method algorithm", "model using method algorithm", "powder nursing methods algorithm", "powder focusing method algorithm", "powder using metal algorithm"
"modified network approximation algorithms" » "certified network approximation algorithms", "defined network approximation algorithms", "modified near approximation algorithms"

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: (("powder using method algorithm") OR ("modified network approximation algorithms"))~.
• Removing quotes may allow a broader search: (( powder using method algorithm ) or ( modified network approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("powder using method algorithm") or ("modified network approximation algorithms"))*.
