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