Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
search algorithm » source algorithm
trinh search » trinh scratch, trinh mach
code trinh » cong trinh, co trinh

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( code trinh search algorithm ) or ( modified parameters optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code trinh search algorithm ) OR ( modified parameters optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( code trinh search algorithm ) or ( modified parameters optimization algorithm ))*.
