Perhaps you should try some spelling variations:
"modified parameters optimization algorithmss" » "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameters optimisation algorithms", "modified parameters estimation algorithmss", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss"
"modified make optimization algorithms" » "modified make optimisation algorithm", "modified make estimation algorithms", "modified make estimation algorithm", "modified market optimization algorithms", "modified game optimization algorithms", "modified stage optimization algorithms", "modified male optimization algorithms"

Try widening your search to All Fields.

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

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