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