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

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