Perhaps you should try some spelling variations:
parameters estimation » parameter estimation, parameter estimates, parameter optimization
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
cui algorithm » our algorithm, _ algorithm, mom algorithm
code than » con than, more than
than cui » than cua, than nui, thanh qui

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

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