Perhaps you should try some spelling variations:
"modified location optimization algorithms" » "modified location optimisation algorithm", "modified location estimation algorithms", "modified location estimation algorithm", "modified allocation optimization algorithms", "modified static optimization algorithms", "modified carbon 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.

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