Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified sphere optimization algorithms" » "modified sphere optimisation algorithm", "modified sphere estimation algorithms", "modified sphere estimation algorithm", "modified sphere optimisation algorithms", "modified sphere estimation algorithmss", "modified stage optimization algorithms", "modified response optimization algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameters optimization algorithm") or ("modified sphere optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithm") OR ("modified sphere optimization algorithms")).
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) or ( modified sphere optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithm") or ("modified sphere optimization algorithms"))*.
