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