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