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"
"modified choosing optimizer algorithm" » "modified choosing optimizer algorithms", "modified choosing optimized algorithm", "modified choosing optimized algorithms", "modified caging optimizer 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 ("modified choosing optimizer algorithm"))~.
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) or ( modified choosing optimizer algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") or ("modified choosing optimizer algorithm"))*.
