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