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