Perhaps you should try some spelling variations:
estimation algorithmss » estimation algorithm, optimization algorithms
parameters estimation » parameter estimation, parameter estimates, parameter optimization
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
response estimation » response optimization, pose estimation, response association
code response » dose response, cell response, host response

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( code response estimation algorithmss ) or ( modified parameters estimation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code response estimation algorithmss ) OR ( modified parameters estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( code response estimation algorithmss ) or ( modified parameters estimation algorithms ))*.
