Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"powder using methods algorithm" » "powder nursing methods algorithm", "powder making methods algorithm", "powder counting methods algorithm", "code using methods algorithm", "boiler using methods algorithm", "model using methods 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: (("modified notion optimization algorithms") OR ("powder using methods algorithm"))~.
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) or ( powder using methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") or ("powder using methods algorithm"))*.
