Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
huy algorithm » our algorithm, _ algorithm, mom algorithm
code van » corne van, cong van
de van » le van, do van, ve van

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

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