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