Perhaps you should try some spelling variations:
"modified location optimization algorithmss" » "modified location optimization algorithms", "modified location optimisation algorithm", "modified location estimation algorithms", "modified allocation optimization algorithmss", "modified static optimization algorithmss", "modified carbon optimization algorithmss"
"modified objective approximation algorithm" » "modified objective 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: (("modified location optimization algorithmss") OR ("modified objective approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified location optimization algorithmss ) or ( modified objective approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified location optimization algorithmss") or ("modified objective approximation algorithm"))*.
