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

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