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