Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
dau algorithm » adam algorithm, _ algorithm, mom algorithm
code phan » co phan, cong phan, de phan
phan dau » phan tu, hang dau

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 phan dau algorithm ) OR ( modified parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( code phan dau algorithm ) or ( modified parameters optimization algorithms ))*.
