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 stochastic optimisation algorithm" » "modified stochastic optimization algorithm", "modified static optimization algorithm", "modified stochastic configuration algorithm", "modified stochastic optimization algorithms", "modified stochastic estimation algorithm", "modified stochastic 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 parameter optimisation algorithmss") OR ("modified stochastic optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameter optimisation algorithmss\") OR (\"modified stochastic optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified parameter optimisation algorithmss ) OR ( modified stochastic optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimisation algorithmss") OR ("modified stochastic optimisation algorithm"))*.
