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