Perhaps you should try some spelling variations:
"modified notion optimisation algorithm" » "modified notion optimization algorithms", "modified notion estimation algorithm", "modified notion estimation algorithms", "modified network optimization algorithm"
"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"

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

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