Perhaps you should try some spelling variations:
"modified parameter optimisation algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss"
"modified static optimisation algorithm" » "modified static optimization algorithms", "modified static estimation algorithm", "modified static estimation algorithms", "modified static optimization algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm"

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

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