Perhaps you should try some spelling variations:
estimation algorithmss » estimation algorithm, optimization algorithms
stochastic estimation » stochastic optimization
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
df estimation » _ estimation
modified df » modified _, modified adam, modified bi1

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

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