Perhaps you should try some spelling variations:
"modified parameter optimisation algorithmss" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimization algorithmsss", "modified parameter estimation algorithmss", "modified parameter estimation algorithmsss", "modified parameter optimization algorithmss"
"modified df optimisation algorithm" » "modified df optimization algorithms", "modified df estimation algorithm", "modified df estimation algorithms", "modified _ optimisation algorithm", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified adam optimisation algorithm", "modified bi1 optimisation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified df optimisation algorithm") OR ("modified parameter optimisation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified df optimisation algorithm\") OR (\"modified parameter optimisation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified df optimisation algorithm ) OR ( modified parameter optimisation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified df optimisation algorithm") OR ("modified parameter optimisation algorithmss"))*.
