Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
source algorithm » our algorithm, search algorithm
code tinh » cong tinh, che tinh
de tinh » den tinh, ve tinh, he tinh

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( ((code tinh) OR (de tinh)) source algorithm ) or ( modified parameters optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((code tinh) OR (de tinh)) source algorithm ) OR ( modified parameters optimisation algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((code tinh) OR (de tinh)) source algorithm ) or ( modified parameters optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( ((code tinh) OR (de tinh)) source algorithm ) or ( modified parameters optimisation algorithm ))*.
