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"
"parameters optimisation algorithmssssssss" » "parameter optimization algorithmssssssss", "parameter estimation algorithmssssssss", "parameters optimization algorithmsssssssss", "parameters estimation algorithmssssssss", "parameters estimation algorithmsssssssss"

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 ("parameters optimisation algorithmssssssss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"stochastic optimisation algorithm\") OR (\"parameters optimisation algorithmssssssss\"))".
• Removing quotes may allow a broader search: (( stochastic optimisation algorithm ) OR ( parameters optimisation algorithmssssssss )).
• Adding a wildcard symbol may retrieve word variants: (("stochastic optimisation algorithm") OR ("parameters optimisation algorithmssssssss"))*.
