Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
khac algorithm » adam algorithm, search algorithm
code pham » che pham, cong pham
pham khac » phap khac, pham khanh, pham khoa

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