Perhaps you should try some spelling variations:
"modified quadratic optimisation algorithmss" » "modified quadratic optimization algorithms", "modified quadratic estimation algorithms", "modified quadratic estimation algorithm", "modified quadratic optimization algorithmss", "modified quadratic optimization algorithmsss", "modified quadratic estimation algorithmss", "modified quadratic estimation algorithmsss"
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified quadratic optimisation algorithmss") or ("modified parameter optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified quadratic optimisation algorithmss") OR ("modified parameter optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified quadratic optimisation algorithmss ) or ( modified parameter optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified quadratic optimisation algorithmss") or ("modified parameter optimisation algorithm"))*.
