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"
"model using methods algorithm" » "model nursing methods algorithm", "model making methods algorithm", "model counting methods algorithm", "code using methods algorithm", "models nursing methods algorithm", "powder 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 ("model using methods algorithm"))~.
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) or ( model using methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") or ("model using methods algorithm"))*.
