Perhaps you should try some spelling variations:
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
cuc algorithm » our algorithm, _ algorithm, mom algorithm
code tich » co tich
tich cuc » tich cac, tich du

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 objective optimisation algorithm ) OR ( code tich cuc algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimisation algorithm ) or ( code tich cuc algorithm ))*.
