Perhaps you should try some spelling variations:
estimates algorithms » estimation algorithms, estimation algorithm, optimized algorithms
parameter estimates » parameter estimation
method algorithm » mom algorithm
export control » error control
control method » control methods

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( export control method algorithm ) or ( modified parameter estimates algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( export control method algorithm ) OR ( modified parameter estimates algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( export control method algorithm ) or ( modified parameter estimates algorithms ))*.
