Perhaps you should try some spelling variations:
"modified objective optimization algorithmss" » "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified multiobjective optimization algorithmss", "modified objective optimization algorithmsss", "modified objective optimisation algorithmss", "modified objective estimation algorithmss"
"modified df optimization algorithm" » "modified df optimization algorithms", "modified df optimisation algorithm", "modified df estimation algorithm", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified _ optimisation algorithm", "modified adam optimization algorithm", "modified bi1 optimization 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 objective optimization algorithmss") or ("modified df optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimization algorithmss") OR ("modified df optimization algorithm")).
• Removing quotes may allow a broader search: (( modified objective optimization algorithmss ) or ( modified df optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithmss") or ("modified df optimization algorithm"))*.
