Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
tu algorithm » our algorithm, _ algorithm, mom algorithm
code phap » de phap, che phap
phap tu » phan tu, pham tu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( code phap tu algorithm ) OR ( modified parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( code phap tu algorithm ) or ( modified parameter optimisation algorithm ))*.
