Perhaps you should try some spelling variations:
multiobjective optimisation » multiobjective optimization, objective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
duc algorithm » our algorithm, adam algorithm, _ algorithm
phan duc » pham duc, phan tu, phan dau
de phan » d phan, de phap, de phat

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified multiobjective optimisation algorithm ) OR ( de phan duc algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified multiobjective optimisation algorithm ) or ( de phan duc algorithm ))*.
