Perhaps you should try some spelling variations:
"modified parameter optimization algorithmssss" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter optimization algorithmsssss", "modified parameter optimisation algorithmssss", "modified parameter estimation algorithmssss", "modified parameters optimization algorithmssss"
"modified static optimization algorithm" » "modified static optimization algorithms", "modified static optimisation algorithm", "modified static estimation algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing 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 static optimization algorithm") or ("modified parameter optimization algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified static optimization algorithm") OR ("modified parameter optimization algorithmssss")).
• Removing quotes may allow a broader search: (( modified static optimization algorithm ) or ( modified parameter optimization algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified static optimization algorithm") or ("modified parameter optimization algorithmssss"))*.
