Perhaps you should try some spelling variations:
"modified notion optimisation algorithm" » "modified notion optimization algorithms", "modified notion estimation algorithm", "modified notion estimation algorithms", "modified network optimization algorithm"
"modified parameter optimizer algorithmss" » "modified parameter optimizer algorithms", "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimization algorithmss"

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 parameter optimizer algorithmss") OR ("modified notion optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified parameter optimizer algorithmss ) or ( modified notion optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimizer algorithmss") or ("modified notion optimisation algorithm"))*.
