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