Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
parameter estimation » parameter estimates, parameter optimization
one algorithm » our algorithm, mom algorithm, source algorithm
_ algorithm » _ algorithms, _ algorithmic, mom algorithm
code » core

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( code using ((one algorithm) OR (_ algorithm)) ) or ( modified parameter estimation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code using ((one algorithm) OR (_ algorithm)) ) OR ( modified parameter estimation algorithms )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code using ((one algorithm) OR (_ algorithm)) ) or ( modified parameter estimation algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( code using ((one algorithm) OR (_ algorithm)) ) or ( modified parameter estimation algorithms ))*.
