Perhaps you should try some spelling variations:
"stochastic estimation algorithms" » "stochastic optimization algorithms", "stochastic estimation algorithm", "stochastic optimisation algorithm"
"parameters estimation algorithmssssssss" » "parameters estimation algorithmsssssss", "parameters optimization algorithmssssssss", "parameters optimisation algorithmsssssss", "parameter estimation algorithmssssssss", "parameter estimates algorithmssssssss", "parameter optimization algorithmssssssss"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("stochastic estimation algorithms") OR ("parameters estimation algorithmssssssss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"stochastic estimation algorithms\") OR (\"parameters estimation algorithmssssssss\"))".
• Removing quotes may allow a broader search: (( stochastic estimation algorithms ) OR ( parameters estimation algorithmssssssss )).
• Adding a wildcard symbol may retrieve word variants: (("stochastic estimation algorithms") OR ("parameters estimation algorithmssssssss"))*.
