Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
huu algorithm » our algorithm, _ algorithm, mom algorithm
code pham » che pham, cong pham
pham huu » pham duc, pham duy, phan huy

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code pham huu algorithm ) OR ( modified parameters optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( code pham huu algorithm ) OR ( modified parameters optimization algorithm ))*.
