Perhaps you should try some spelling variations:
"stochastic optimisation algorithmss" » "stochastic optimization algorithms", "stochastic estimation algorithms", "stochastic estimation algorithm", "stochastic optimization algorithmss", "static optimization algorithmss", "stochastic configuration algorithmss", "stochastic optimization algorithmsss", "stochastic estimation algorithmss", "stochastic estimation algorithmsss"
"parameter optimisation algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameter optimization algorithms", "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: (("stochastic optimisation algorithmss") or ("parameter optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("stochastic optimisation algorithmss") OR ("parameter optimisation algorithm")).
• Removing quotes may allow a broader search: (( stochastic optimisation algorithmss ) or ( parameter optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("stochastic optimisation algorithmss") or ("parameter optimisation algorithm"))*.
