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