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