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