Perhaps you should try some spelling variations:
"modified passive optimization algorithmssss" » "modified passive optimization algorithms", "modified passive optimisation algorithm", "modified passive optimization algorithmsssss", "modified passive optimisation algorithmssss", "modified passive estimation algorithmssss", "modified bayesian optimization algorithmssss", "modified game optimization algorithmssss", "modified policy optimization algorithmssss", "modified adaptive optimization algorithmssss"
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"

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 passive optimization algorithmssss") or ("modified parameter optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified passive optimization algorithmssss") OR ("modified parameter optimization algorithm")).
• Removing quotes may allow a broader search: (( modified passive optimization algorithmssss ) or ( modified parameter optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive optimization algorithmssss") or ("modified parameter optimization algorithm"))*.
