Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
ma algorithm » mom algorithm, _ algorithm, adam algorithm
code pham » che pham, cong pham
pham ma » pham va, pham van, pham tai

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 pham ma algorithm ) OR ( modified parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( code pham ma algorithm ) or ( modified parameter optimisation algorithm ))*.
