Perhaps you should try some spelling variations:
"modified parameters optimization algorithmss" » "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss", "modified parameters optimisation algorithms", "modified parameters estimation algorithmss"
"modified df optimization algorithms" » "modified df optimisation algorithm", "modified df estimation algorithms", "modified df estimation algorithm", "modified _ optimization algorithms", "modified qoe optimization algorithms", "modified _ optimisation algorithms", "modified adam optimization algorithms", "modified bi1 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 algorithmss") OR ("modified df optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameters optimization algorithmss\") OR (\"modified df optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified parameters optimization algorithmss ) OR ( modified df optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithmss") OR ("modified df optimization algorithms"))*.
