Perhaps you should try some spelling variations:
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
duc algorithm » our algorithm, adam algorithm, _ algorithm
code than » con than, more than
than duc » tran duc, phan duc, than doc

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified objective optimisation algorithm ) or ( code than duc algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified objective optimisation algorithm ) OR ( code than duc algorithm ))*.
